## Other questions in this quiz

## 2. 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

## 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. As a solid melts:

- its temperature stays the same
- its temperature decreases
- its temperature increases

## 5. 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?

- 33.4 kJ
- 33,400 kJ
- 3.34 kJ
