Answer 2

AnswErs :-

1. Evaporation is called as

(a) Surface phenomenon

2. Boiling process is

(b) Bulk phenomenon

3. The state of matter which is found to be more stable at lower temperature

(a) Solid

4. When water gets solidified into ice, then heat is

(b) Evolved

5. Which condition out of the following will increase the evaporation of water ?

(a) Increase in temperature

Extra Information :-

1. Evaporation takes place from the surface and not from the bulk. Thus, it is a surface phenomenon.

2. Heat energy goes to the bulk of liquid and it starts boiling. Thus, it is a bulk phenomenon.

3. At low temperature, the solid state has the lowest chemical potential is the most stable phase.

4. Here, the process is freezing. During freezing, the energy lost by water molecules is gained by the surrounding molecules.

5. On increasing the temperature, kinetic energy increases and more particles get enough kinetic energy to go into the vapour state.
