Chp 10 Thermal Properties of Matter

Internal energy

Energy store that is made up of the total kinetic energy associated with the motion of particles and the total potential energy between the particles in the system

Heat capacity

Change of its internal energy per unit change in its temperature

Specific heat capacity

Change of its internal energy per unit mass for each unit change in its temperature

Latent heat

Energy released or absorbed to change the state of a substance at constant temperature

Latent heat of fusion

The amount of energy transferred to change a substance between the solid and liquid states, at constant temperature

Specific latent heat of fusion

Amount of energy transferred per unit mass of a substance to change between the solid and liquid states, at constant temperature

Specific latent heat of vaporisation

The amount of energy transferred per unit mass of a substance to change it between the liquid and gaseous states, at constant temperature
