Molecules in a liquid must overcome intermolecular forces before they can evaporate. The molecules must also be moving in the right direction and located near the surface in order for evaporation to occur.

When you evaporate sweetened tea the sugar will evaporate with the water?
Only rare molecules of sugar can be trained in the atmosphere by water molecules.
Why does a liquid not evaporate if you store it in a sealed jar?
It has nowhere to evaporate to. Evaporation is dispersion of molecules.
Why has to happen to the water molecules before they can evaporate?
These molecules gain sufficient energy to escape into atmosphere.
Why is energy required to evaporate a liquid?
So the molecules move faster.
Do water molecules that move with higher energy evaporate?
Yes, it is true.
Can water molecules evaporate at the surface or below the surface?
water molecules can evaporate at the surface but not below the surface

Why do solvent molecules evaporate easily?
because it did...
Why has to happen to the water molecules before they can evaporate?
These molecules gain sufficient energy to escape into atmosphere.
What happen to the molecules of the water when it is exposed to sun rays?
The temperature increase and the motion of molecules is accelerated.
How the water changes from gas to liquid?
The water molecules evaporate to the air.
Do water molecules that move with higher energy evaporate?
Yes, it is true.
Why is energy required to evaporate a liquid?
So the molecules move faster.
Do water molecules with highest energy evaporate first?
Yes, it is correct.
What do water molecules have to gain in order to evaporate from liquid water?
Heat
What happens when water molecules when heat is added to water molecules?
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.
