Explanation:
Detailed explanation-1: -Transpiration is the evaporation of water from plants that occurs in the leaves during photosynthesis, when stomata open and CO2 and O2 pass through. As the temperature rises, the water evaporates faster, so plants sweat faster at higher temperatures.
Detailed explanation-2: -Temperature-increasing temperature increases the rate of transpiration because more heat energy means that the water molecules have more kinetic energy and will diffuse faster out of the stomata. This increases the water potential gradient between the inside and outside of the leaf.
