Why can water be a good insulator within the body of endothermic (warm-blooded) animals?
  1. adhesive properties
  2. surface tension
  3. heat of vaporization
  4. specific heat capacity

The unique properties of water are important in biological processes. For the following three properties of water, define the property and give one example of how the property affects living organisms:
  1. cohesion
  2. adhesion
  3. high heat of vaporization
  1. Cohesion is the attraction between the water molecules, which helps create surface tension. Insects can walk on water because of cohesion. Adhesion is the attraction between water molecules and other molecules. Water moving up from the roots of plants to the leaves as a result of capillary action is because of adhesion. Heat of vaporization is the amount of energy required to convert liquid into gas. This property helps humans maintain homeostasis of body temperature by evaporation.
  2. Cohesion is the attraction between water and other molecules, which help create surface tension. Insects can walk on water because of cohesion. Adhesion is the attraction between water molecules. Water moving up from the roots of plants to the leaves as a result of capillary action is because of adhesion. Heat of vaporization is the amount of energy required to convert liquid into gas. This property helps humans maintain homeostasis of body temperature by evaporation.

Adhesion is the attraction between water molecules and other molecules. Water moving up from the roots of plants to the leaves as a result of capillary action is because of adhesion. Heat of vaporization is the amount of energy required to convert solid into gas. This property helps humans maintain homeostasis of body temperature by evaporation.
