heat 1 the quality of being hot; hotness: in physics, heat is considered a form of energy existing as the result of the random motion of molecules and is the form of energy that is transferred between bodies as a result of their temperature difference.  much hotness; great warmth: stifling heat.

Heat This article is about a mode of transfer of energy. For other uses, see Heat (disambiguation). In physics, heat is the amount of energy flowing from one body to another spontaneously due to their temperature difference, or by any means other than through work or the transfer of matter.

- Notice that increasing the kinetic energy of the atoms weakens their bonds. Heating increases the motion of atoms and causes the matter to go from solid (ice) to liquid (water) to gas (vapor). Atomic theory is the field of physics that describes the characteristics and properties of atoms that make up matter.

What is thermal creep? Thermal is a type of scientific term used in science. It is usually connected with a word so as an example: thermal energy = a type of energy or thermal socks = warm socks. Ev…entually you'll notice thermal has almost always something to do with heat and temperature.

heat Absorption of energy by a system as heat takes the form of increased kinetic energy of its molecules, thus resulting in an increase in temperature of the system. Heat is transferred from one system to another in the direction of higher to lower temperature. See also thermodynamics. See Note at temperature.

Heat Radiation Radiation is one of the three basic methods of heat transfer, the other two methods being conduction and convection. See Conduction (heat), Convection (heat), Heat transfer. A hot plate at 260°F (400 K) may show no visible glow; but a hand which is held over it senses the warming rays emitted by the plate.

Water heating Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses. Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers. These metal vessels that heat a batch of water do not produce a continual supply of heated water at a preset temper

Heat of Combustion The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The energy value is a characteristic for each substance.

specific heat specific heat. 1. The ratio of the amount of heat needed to raise the temperature of a certain amount of a substance by one degree to the amount of heat needed to raise the temperature of the same amount of a reference substance, usually water, by one degree.

Latent heat Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization.

What is Heat? To review, temperature is a measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. If two objects-or if a system and its surroundings-have a different temperature, then they have a different ability to transfer heat.

Electric heating Electric heating is a process in which electrical energy is converted to heat. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts electric current to heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy.

heat heat definition In physics, a form of energy associated with the movement of atoms and molecules in any material. The higher the temperature of a material, the faster the atoms are moving, and hence the greater the amount of energy present as heat.

- Convection: is the transfer of heat through fluids (gases or liquids) from a warmer spot to a cooler spot. The particles in fluids (liquids or gases) can move from place to place when heated. Convection occurs when particles with a lot of heat energy move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection.

resistance heating Resistance heating. The generation of heat by electric conductors carrying current. The degree of heating for a given current is proportional to the electrical resistance of the conductor. If the resistance is high, a large amount of heat is generated, and the material is used as a resistor rather than as a conductor.
