    ANSWER :

    1) High specific heat- aquatic habits do not vary much in temperature

    2) Cohesion- water moves up trees due to capillary action

    3) solid form is less dense than liquid- insulates aquatic habitats

    4) high heat of vaporization- evaporative cooling

    EXPLANATION:

    1) Water has a high specific heat, defined as amount of heat required to raise the temperature of one gram of a substance by one degree Celsius. Because of this high specific heat, water can minimize changes in temperature and so aquatic habits do not vary much in temperature.

    2) Water moves up trees due to capillary action which is important for moving water around. Capillary action is the movement of water within the spaces of a porous material due to adhesion, cohesion forces and surface tension.

    Capillary action occurs as water is sticky and cohesion force which helps water molecules to stay close together. Adhesion helps water molecules to attract and stick to other substances. Adhesion of water to the walls of vessel makes upward force. The surface tension holds the surface intact. Water moves up trees due to capillary action when the adhesion to the walls is stronger than the cohesive forces between the water molecules.

    3) Water has one most important property which solid form is less dense than liquid that insulates aquatic habitats. As solid water is less dense, therefore ice floats on the surface of a lake that insulates the water below from freezing and useful to aquatic organisms.

    4) Water has a high heat of vaporization, which is defined as the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Therefore when water molecules evaporate, the surface they evaporate from gets cooler, called as evaporative cooling.
