Water can sometimes move against gravity in tight spaces such as in plant stems. This movement is called

• capillary action

• specific heat

• surface tension

• hydroversion

Water is a polar molecule. This means that it

• loses heat quickly

• has small electrical charges on either end

• is found mostly at polar ice caps

• can exist in many different forms
