Why is that gases are more compressible than liquids ?
Why do solids have a fixed volume & a definite shape?
Why do we wear cotton clothes in summer?
Answers
1. If we put pressure on a solid or a liquid, there is essentially no change in volume. ... The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.
2. Solids have a definite volume and shape because particles in a solid vibrate around fixed locations. Behavior of Solids: Solids have a definite volume and shape because particles in a solid vibrate around fixed locations.
3. We sweat more in the summer session. Cotton is a strong water absorber helps to absorb the sweat and introduce to the environment of evaporation. Our body takes out heat as the sweat evaporates from our body.
Hope it helps you.
Answer:
as the molecules of the gass is more loosely packed than liquids
Due to their highly packed molecules as in solids the molecules are very tightly packed due to which they have definite shape and volume
We wear cotton cloths in summer as it allows air to go in and out easily and it let our body heat to go out
