What type of clothes should we wear in summer?

Solution
- We should wear cotton clothes in the summer. During summers, we sweat more, and cotton is a good absorber of water.
- Thus, it absorbs sweat from our body and exposes the liquid to the atmosphere, making evaporation faster.
- During this evaporation, particles on the liquid's surface gain energy from our body's surface, cooling the body.

The scientists now say that there are actually five states of matter A, B, C, D and E. The state A has a fixed volume but no fixed shape. The state B can be compressed very easily by applying pressure and state C has a fixed shape as well as a fixed volume. The state D is a mixture of free electrons and ions whereas state E is named after an Indian scientist and a famous physicist.
