chapter 11 - thermal properties*

Question 1

what is heat capacity ?

Answer 1

amount of thermal energy required to raise temperature by 1K or 1°c

Question 2

formula for heat capacity ?

Answer 2

C = Q (thermal energy required) / ∆θ (change in temperature)

Question 3

true or flase ? mass effects heat capacity

Answer 3

true

Question 4

what is specific heat capacity ?

Answer 4

specific heat capacity is amt of thermal energy required to raise the temperature of a unit mass (e.g 1kg of substance by 1K or °C

Question 5

formula for specific heat capacity ?

Answer 5

c = C (heat capacity) / mass OR 1/m [Q (thermal energy required) / ∆θ change in temp]

Question 6

what does total internal potential energy effect

Answer 6

effects interatomic or intermolecular forces relates to change of state

Question 7

internal kinetic energy effects what ?

Answer 7

effects motion of particles, temperatures

Question 8

what is the thermal energy absorbed during melting called

Answer 8

latent heat of fusion

Question 9

what is boiling

Answer 9

process where thermal energyvis absorbed by substance, changes it from liquid →gas without change in temp
