WebEvaporation. Evaporation is the process in which a liquid changes to the gaseous state as the free surface, below its boiling point, through the transfer of energy. Evaporation is a cooling process- the latent heat of vapourisation (~585 cal/g of evaporated water) must be provided by the water body. Rate of evaporation depends on. WebOne way to measure the rate of transpiration in a plant is to perform an experiment using a potometer. A potometer is a device that measures the rate of water movement through a plant. It consists of a tube that is connected to a plant, with a reservoir of water at one end and a measurement scale at the other end.

WebThe devices used to measure evapotranspiration are as follows: 1. Lysimeters: It permit the specific measurement of ET, rainfall and water uptake by plants. Lysimeter are tanks, buried in the ground to measure the percolation of water through soils. Lysimeter are the most dependable means of directly measuring the evapo-transpiration rate. Web20 jun. 2024 · Hence, the rate of transpiration is higher in stronger intensity of light and lower in the dark. Temperature: Rate of transpiration is directly proportional to temperature. High temperature increases the rate of transpiration up to a certain limit. The stomata are found to remain open at high temperature even in the dark.
