Question

Gases can be compressed, but liquids cannot.
Which statement explains this difference?
A Each molecule in a gas is more compressible than each molecule in a liquid.
B Molecules in a gas are further apart than molecules in a liquid.
C Molecules in a gas attract each other more strongly than molecules in a liquid.
D Molecules in a gas move more slowly than molecules in a liquid.

Answer 1

Option B is the right one...

Reason:

Gases are compressible bcz of the large inter-molecular distance between them.

Explanation for why other statements are wrong:

A) is wrong bcz each molecule of any state is NOT compressible. Gas can be compressible only bcz of the space BETWEEN the molecules

C) is wrong bcz inter-molecular attraction is more stronger in liquids than in gases(real gases)(no force of attraction in ideal gases)

D) is wrong bcz Molecules in a gas move more rapidly than molecules in a liquid. And it's bcz of large inter-molecular distance btw the molecules of the gas

I hope it helped u
