Water — practice question

The specific heat capacities of several substances are given. Which statement is correct?

  • AAir is a more stable environment than water because it is more resistant to changes in temperature.
  • BIt takes more energy to raise the temperature of hydrogen gas than it does to raise the temperature of water.
  • CA specific heat capacity of $4.2\,\text{J g}^{-1}\,^{\circ}\text{C}$ means that it takes $4.2\,\text{J}$ of energy to vaporise $1.0\,\text{g}$ of liquid water.
  • DThere are more hydrogen bonds between water molecules in a gas than between water molecules in a liquid.
