Subliming

Question 6

Name of process turning gas to solid

Answer 6

Deposition

Question 7

Where does the energy for tropical storms predominantly come from?

Answer 7

The condensation of water vapour

Question 8

Why does the temperature not increase during state change?

Answer 8

Because the energy is instead used to change the matter by breaking bonds and attractive forces

Question 9

What is specific latent heat of fusion

Answer 9

The energy transferred when 1kg of a substance changes from the solid state to the liquid state or vice versa

Question 10

What is specific latent heat of vaporisation

Answer 10

The energy transferred when 1kg of a substance changes from liquid to gas

Question 11

Equation for specific latent heat (word)

Answer 11

Thermal energy for a change in state (J) = mass (kg) x specific latent heat (J/kg)

Question 12

How is latent heat different to specific heat capacity?

Answer 12

Latent heat is about change of state, heat capacity is about change in temperature
