Question 1

Change in thermal energy is measured in:

Answer 1

Joules (J)

Question 2

Mass is measured in:

Answer 2

kilograms (kg)

Question 3

Specific heat capacity is measured in:

Answer 3

Joules/kilograms degrees celcius (J/kg°C)

Question 4

Change in temperature is measured in:

Answer 4

degrees celcius (°C)

Question 5

Change in thermal energy calculation

Answer 5

Change in thermal energy = mass x specific heat capacity - change in temperature

Question 6

Thermal energy needed for a change of state calculation

Answer 6

thermal energy need for change of state = mass x specific latent heat
