- n the passage of gases through fine tubes because of differences in pressure or temperature
- n the process of giving off or exhaling water vapor through the skin or mucous membranes
- n the emission of water vapor from the leaves of plants
- Going back to the same leaves daily, he keeps a record of their transpiration rate.
