Thermal Energy Flashcards

Thermal Energy

the sum of a particles’ kinetic and potential energies

Thermal Equilibrium

is the state in which the rate of thermal energy transfer between two objects are equal & the objects are at the same temp

Heat

is the transfer of thermal energy, which occurs spontaneously from a hotter object to a cooler object

Convection

transfer of heat caused by the motion of fluid in a liquid or gas due to temp. differences

Radiation

the transfer of heat through a vaccum

Conduction

the transfer of heat through a substance by direct contact

Specific Heat

the amount of heat required to raise the temp of 1 kg of a substance by 1 degree K

Heat of Fusion

the amount of thermal energy needed to melt a substance from a solid to a liquid

Heat of Vaporization

the thermal energy needed to vaporize a liquid

Temperature

is a measure of the average kinetic energy of a substance

Heat Capacity

the amount of thermal energy required to raise the temperature of an entire object or system by 1 Kelvin,

melting point

is the temperature at which a solid turns into a liquid.

freezing point

is the temperature at which a liquid turns into a solid.
