Heat and temperature

Temperature

It is the measure of the hotness or coldness of a body

Thermometric property

It is any physical property that changes measurably with temperature

Specific heat capacity

It is the heat energy needed to change the temperature of 1 kg of a substance by 1 kelvin

Latent heat

It is the heat energy needed to change the state of 1 kg of a substance without a change in temperature

Latent heat of fusion

It is the change from solid to liquid

Latent heat of vaporiastion

It is the change from liquid to gas

Heat pump

It is a device that uses electricity to transfer heat from a cooler region to a warmer one

Conduction

It is the movement of heat energy through a substance by the passing on of molecular vibrations. There is no overall motion of the substance

U-value

It is the amount of heat energy conducted per second through 1m² of a structure when a temperature difference of 1 K is maintained between both ends

Convection

It is the transfer of heat through a fluid by means of circulating currents of fluid caused by the heat

Radiation

It is the transfer of heat energy from one place to another in the form of electromagnetic waves
