Detailed explanation-1: -These escaping molecules carry heat along with their escape, causing the slower moving water molecules left behind to cool. Sweating is an example of this property, as the water molecules in sweat absorb the heat from the body and move faster, allowing them to vaporize.

Detailed explanation-2: -Evaporation has a cooling effect. When a molecule evaporates it separates from other molecules in a liquid and becomes a vapour molecule. Large amounts of heat are needed to evaporate water, because H-bonds need to be broken. Sweating is an example of using water as a coolant.

Detailed explanation-3: -Water has a high specific heat capacity-it absorbs a lot of heat before it begins to get hot.

Detailed explanation-4: -Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range.
