List the external factors that affect the rate of transpiration

Here are the external factors that affect the rate of transpiration:

Temperature directly influences the rate of evaporation; higher temperatures increase the kinetic energy of water molecules, leading to faster transpiration. Humidity in the surrounding air affects the water potential gradient; lower humidity creates a steeper gradient, causing water to diffuse out of the leaf more rapidly. Wind speed removes the humid air layer around the leaf, maintaining a steep water potential gradient and thus increasing transpiration. Lastly, light intensity promotes the opening of stomata for photosynthesis, which in turn allows more water vapor to escape.
