Why do you feel cool under a tree but not so under a tin shed on a sunny day?
-
- The greenness of the tree gives the cool feeling.
- Photosynthesis absorbs heat
- The leaves convert water vapors into water which is a heat-absorbing process
- The leaves give out water which vaporizes absorbing some heat as latent heat.
Correct Option: D
The transpiration occurs from the leaves, all the time. The water released from leaves absorbs heat from the surrounding atmosphere to vaporizer so the area become cool.
