Question

how does evaporation cause cooling ? compare the process of boiling and vaporization​

Answer 1

Answer:

Water vapour comes in contact with a cooler surface and releases the heat stored in it. Due to the loss of heat, water vapour condenses to form small liquid droplets on the same surface.

Answer 2

Answer:

Evaporation is a surface phenomenon where any liquid can release its molecules in the air by using the surrounding heat or the heat from the liquid itself. It is because the water molecules absorb the heat of our body and convert into gas molecules. The heat lost from our skin makes us feel cooler.

Vaporization (or vapourisation) of an element or compound is a phase transition from the liquid phase to vapor. There are two types of vaporization: evaporation and boiling.  

BOILING

The term Boiling is defined as the process in which the liquid phase changes to gaseous phase at a constant temperature is called as Boiling. The point where the liquid changes into gaseous state at a given pressure and temperature is called as ‘Boiling Point’. The boiling point of the water is 100°c at normal atmospheric pressure.

EVAPORATION

The term Evaporation is defined as the process of escaping of liquid molecules from the surface of a liquid at any temperature is called evaporation. The rate of evaporation of a liquid depends on its surface area, temperature and amount of water vapour present in the surronding air
