2. Energy = mass x specific latent heat. If the specific latent heat of melting of water is 334 kJ/kg, how much energy is needed to melt 100 g of ice?

  • 3.34 kJ
  • 33.4 kJ
  • 33,400 kJ

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

  • Lead melts at a low temperature
  • 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

4. Which equation is correct?

  • energy = mass x specific latent heat x temperature
  • energy = mass x specific heat capacity x change in temperature
  • energy = mass x specific heat capacity x temperature

5. Which statement about units is correct?

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