Answer:
Explanation:
cohesive property of water molecules produce surface tension which helps water flow upward from a plant's roots to leaves in narrow tube . The narrower the tube , the higher the water level rises.
Lakes do not freeze in winter because water starts reducing its density below 4 degree centigrade so it starts floating on the surface in the form of ice or ice chilled water and blocks the evolution of heat from within the lake.
Evaporation from surface of leaf keeps the plants cool by the process of absorption of latent heat of vaporization from leaves which is very high for water. Water has maximum latent heat of vaporization.
Cells resist temperature changes because enzymes which are necessary for metabolic activity are active only within a temperature range.
