Comment on the experimental setup shown in the image. What will happen to the level of mercury if a blower is placed close to the setup?

(N/A) The experimental setup shown is a potometer,which is used to measure the rate of transpiration in a leafy shoot.
When a blower is placed close to the setup,it increases the speed of air movement around the leaves.
Increased air movement reduces the humidity around the leaf surface,which in turn increases the rate of transpiration.
As the rate of transpiration increases,the leafy shoot absorbs water more rapidly from the tube.
This increased water uptake creates a stronger pull (transpiration pull),causing the mercury level in the tube to rise.
