2. The specific latent heat of melting for lead is 22.4 kJ/kg and that of oxygen is 13.9 kJ/kg. This means:

  • more energy is needed to melt lead than is needed to melt oxygen
  • more energy is needed to heat lead than is needed to heat the same mass of oxygen by the same amount
  • lead melts at a high temperature

3. The specific heat capacity of water is 4181 J/kg/°C and that of lead is 128 J/kg/°C. This means:

  • More energy is needed to heat water than is needed to heat the same mass of lead by the same amount
  • More energy is needed to boil water than is needed to boil lead
  • Lead melts at a low temperature

4. Which statement about units is correct?

  • Temperature is measured in °C and energy in K
  • Temperature is measured in J and energy in °C
  • Temperature is measured in °C and energy in J
  • Temperature is measured in °C and energy in W

5. As a solid melts:

  • its temperature increases
  • its temperature stays the same
  • its temperature decreases
