Specific Heat Capacity

Specific heat is the energy required to change the temperature of 1 kg of a substance by 1 C at constant pressure.

Specific heat is related to energy transferred, mass and temperature change by this equation:

Thermal Conduction

Thermal conduction is the transfer of energy as heat through a material by particle collisions.

Substances that rapidly transfer energy as heat are called thermal conductors. Examples : Metals

Substances that slowly transfer energy as heat are called thermal insulators. Examples : asbestos, cork, ceramic, cardboard,

fiberglass

Methods of Energy Transfer

Convection – displacement of cold matter by hot matter

Radiation – use of electromagnetic radiation to reduce internal energy
