thermal properties of matter

Question 1

internal energy

Answer 1

the sum of energy due to the vibration of the particles (KE) and the stretching and compressing of intermolecular bonds (PE)

Question 2

(specific) heat capacity

Answer 2

amt of thermal energy required (per unit mass) to raise the temp of a substance by a unit temp

Question 3

latent heat

Answer 3

amt of thermal energy absorbed or released during a change of state without a change in temp

Question 4

(specific) latent heat of fusion

Answer 4

amt of thermal energy required (per unit mass) to change a substance from solid to liquid state, or vice versa, without a change in temp

Question 5

(specific) latent heat of vaporisation

Answer 5

amt of thermal energy required (per unit mass) to change a substance from liquid to gaseous state, or vice versa, without a change in temp
