High specific heat capacity: this means a large amount of heat energy is needed to raise its temperature. This is because the hydrogen bonds between water molecules restrict their movement, resisting an increase in kinetic energy and therefore, resisting an increase in temperature. This prevents large fluctuations in water temperature, which is important in keeping aquatic habitats stable, so that organisms do not have to adapt to extremes of temperature. It also allows enzymes within cells to work efficiently. High latent heat of vaporisation: this means a lot of heat energy is needed to change t from a liquid to a vapour. This is important, for example, in temperature control, where heat is used to vaporise water from sweat on the skin or from a leaf's surface. As the water evaporates, the body ______.
