What happen to water moulcule as heat is applied?

When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.

Will water without salt evaporate faster than water without salt?

Yes, because when salt is put into water, they can also act like magnets. Attaching to opposite particles. The salt molecules also push down the water molecules so the water molecules have to get enough power to evaporate. Which makes plain water evaporate faster.


What is the process through which water is lost through the plant's stoma?

Evaporation. Water molecules have a cohesive property, so as water molecules closest to the stoma evaporate and diffuse through the stoma they will pull the water molecules from the xylem behind them. These water molecules will evaporate too and draw more water up.


What makes water evaporate except heat?

This is the continuous movement of water molecules.
