If only life were as easy as in the halcyon days of year 7, where one could simply bung your beaker-load of 'stuff' over a Bunsen and hope for the best If heating is required, this should be stated, with suitable temperature if this is critical 'Reflux' is not taken to imply heating Think about what else you need to add to that to make the conditions clear The use of room temperature should be explicitly (clearly) stated if this is the correct condition
Heating is the system and equipment that is used to heat a building. I wish I knew how to turn on the heating. see also central heating. a system for making a room or building warm American Equivalent: heat central heating. Process of raising the temperature of an enclosed space. Heat can be delivered by convection, radiation, and thermal conduction. With the exception of the ancient Romans, who developed a form of central heating, most cultures relied on direct heating methods such as fireplaces and stoves. Central heating, adopted for use again in the 19th century, is a method of indirect heating: heat is produced away from the occupants and then conveyed to them. In warm-air heating, air heated by a furnace rises through ducts to rooms above, where it is emitted through grills. In hot-water systems, a pump circulates water from a boiler through a system of pipes to radiators or convectors in rooms. In steam systems, steam is generated in the boiler and led to radiators through pipes. The high temperature of the steam makes it hard to control, and steam heating has been largely superseded. A common type of electric heating system converts electric current to heat by means of resistors that emit radiant energy. See also radiant heating, solar heating. induction heating radiant heating solar heating
Heat is usually transferred by radiation, conduction, or convection In air drying wood, some heat is provided by direct radiation from the sun but the major heat source is by convection of the surrounding air In conventional kiln drying, heat is transferred to the wood by forced convection by means of a fan system
Heating is the process of heating a building or room, considered especially from the point of view of how much this costs. You can still find cottages for £150 a week, including heating. heating bills

utility to warm a building; "the heating system wasn't working"; "they have radiant heating"
The heating value or calorific value of a substance, usually a fuel or food, is the amount of heat released during the combustion of a specified amount of it. The calorific value is a characteristic for each substance. It is measured in units of energy per unit of the substance, usually mass, such as: kcal/kg, kJ/kg, J/mol, Btu/m³. Heating value is commonly determined by use of a bomb calorimeter
Central heating is a heating system for buildings. Air or water is heated in one place and travels round a building through pipes and radiators. a system of heating buildings in which water or air is heated in one place and then sent around the rest of the building through pipes etc

capacity - Ratio of heat absorbed or released to the corresponding temperature rise or fall Also called thermal capacity Highlights - Areas of bright tone on an image High-pass filter - A filter, which selectively enhances contrast variations with high spatial frequencies in an image It improves the sharpness of images and is a method of edge enhancement I
Heat is defined as energy in the process of being transferred from one object to another because of the temperature difference between them In the atmosphere, heat is commonly transferred by conduction, convection, advection and radiation
energy transferred between two objects because of a temperature difference; the thermal motion of atoms and molecules For chemical systems the sign for heat flow into the system is positive, because this process increases the internal energy of the system Heat flowing out of the system is defined to be negative, since this process decreases the internal energy of the system
The transfer of energy from one object at a higher temperature to another object at a lower temperature Heat can be transferred by conduction, convection, or radiation Although technically incorrect, the word heat is often used to mean "thermal energy "
In the cgs system, one calorie is the amount of heat needed to raise the temperature of one gram of water by one degree Celsius In mks units, the amount of heat to raise the temperature of one kilogram of water by one degree Celsius is equal to one kilocalorie The SI system uses the joule as a unit of heat as well as a unit of work In English units, the British thermal unit (Btu) is the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit The Btu is the larger unit, as 1 Btu equals 252 calories The fact that heat is a form of energy can be seen from the use of the joule; 1 calorie is equivalent to 4 19 J One joule equals 0 24 calorie
intense passion or emotion the sensation caused by heat energy a preliminary race in which the winner advances to a more important race a form of energy that is transferred by a difference in temperature make hot or hotter; "heat the soup"
A form of energy transferred between two systems by virtue of a difference in temperature The first law of thermodynamics demonstrated that the heat absorbed by a system may be used by the system to do work or to raise its internal energy

A heat is one of a series of races or competitions. The winners of a heat take part in another race or competition, against the winners of other heats. the heats of the men's 100m breaststroke. see also dead heat
arouse or excite feelings and passions; "The ostentatious way of living of the rich ignites the hatred of the poor"; "The refugees' fate stirred up compassion around the world"; "Wake old feelings of hatred"
When a female animal is on heat in British English, or in heat in American English, she is in a state where she is ready to mate with a male animal, as this will probably result in her becoming pregnant. to make something become warm or hot = warm up. Energy transferred from one body to another as the result of a difference in temperature. Heat flows from a hotter body to a colder body when the two bodies are brought together. This transfer of energy usually results in an increase in the temperature of the colder body and a decrease in that of the hotter body. A substance may absorb heat without an increase in temperature as it changes from one phase to another that is, when it melts or boils. The distinction between heat (a form of energy) and temperature (a measure of the amount of energy) was clarified in the 19th century by such scientists as J.-B. Fourier, Gustav Kirchhoff, and Ludwig Boltzmann. heat capacity heat exchanger heat exhaustion heat prostration heat pump heat treating latent heat reaction heat of specific heat induction heating radiant heating solar heating

In common usage, the term is generally applied to the storage of thermal energy in a body as internal energy, both potential and kinetic More specifically, it is defined as energy in transition due to a temperature difference
As defined in thermodynamics, heat is the energy that flows between two systems as a result of °temperature differences (a system contains neither heat nor °work, but can produce heat or do work) Heat thus differs from °thermal energy
That which is transferred from a hot body to a cold body It is important not to think of heat as a form of energy but as a transfer of energy from one place to another See the First Law By convention, heat entering the system from the environment is positive, heat leaving the system to the environment is negative
Method of raising the temperature of an electrically conductive material by subjecting it to an alternating electromagnetic field. Energy in the electric currents induced in the object is dissipated as heat. Induction heating is used in metalworking to heat metals for soldering, tempering, and annealing, and in induction furnaces for melting and processing metals. The principle of the induction-heating process resembles that of the transformer. A water-cooled coil (inductor), acting as the primary winding of a transformer, surrounds the material to be heated (the workpiece), which acts as the secondary winding. Alternating current flowing in the primary coil induces eddy currents in the workpiece, causing it to become heated. The depth to which the eddy currents penetrate, and therefore the distribution of heat within the object, depend on the frequency of the primary alternating current and the magnetic permeability, as well as the resistivity, of the material
Heating system in which heat is transmitted by radiation from a heated surface. Radiant heating systems usually employ either electric-resistance wiring or hot-water heating pipes, which may embedded in the floor, ceiling, or walls. Panel heating is a form of radiant heating characterized by very large surfaces (typically an entire ceiling or floor) containing electrical conductors, hot-water pipes, or hot-air ducts. With many such systems there is no visible heating equipment in the room
Use of solar radiation to heat water or air in buildings. There are two types: passive and active. Passive heating relies on architectural design; the building's siting, orientation, layout, materials, and construction are utilized to maximize the heating effect of sunlight falling on it. A well-insulated building with a large south-facing window, for instance, can trap heat on sunny days and reduce reliance on gas, oil, or electricity. Brick, stone, or tile capacity walls are often incorporated to absorb the sun's energy and radiate it into the interior, usually after a time lag of several hours. In active solar heating, mechanical means are used to collect, store, and distribute solar energy. In liquid-based systems, a blackened metal plate on the exterior absorbs sunlight and traps heat, which is transferred to a carrier fluid. Alternatively, fluid may be pumped through a glass tube or volume of space onto which sunlight has been focused by mirrors. After picking up heat from the collector, the warm fluid is pumped to an insulated storage tank. The system can supply a home with hot water from the tank or provide space heating with the warmed water flowing through tubes in floors and ceilings
