Question

Solids are usually:

less dense than gases
more dense than liquids
equal in density to other phases

Answer 1

Solids are usually more dense than liquids. There are few cases where solids are less dense than liquids, one being water. This is why ice floats in water :)

Hope this helps

Answer 2

Answer: Option (b) is the correct answer.

Step-by-step explanation:

In solids, there occurs strong intermolecular forces of attraction between the particles due to which they are held much closer to each other. As a result, they solids have fixed shape and volume.

On the other hand, particles in a liquid are less closer to each other as compared to solids. Hence, liquids do not have a fixed shape but they have a fixed volume. Liquids take the shape of container in which they are placed.

Whereas particles of a gas are held by weak Vander waal forces and they are far apart from each other. Hence, they have high kinetic energy and collide rapidly with each other.

Therefore, we can conclude that solids are usually more dense than liquids.
