Question

Which of the following options indicates the relative randomness of molecules in the three states of matter?

• A. Solid > liquid > gas
• B. Liquid < solid < gas
• C. Liquid > gas > solid
• D. Gas > liquid > solid
• E. None of the above

Answer 1

The correct option is D Gas > liquid > solid

Gas > liquid > solid

Gas particles have the highest kinetic energy, hence, the randomness is highest in gas as molecules of a gas are far apart from each other.

The liquid particles interaction with each other, due to which liquid has lesser randomness than a gas.

The solid particles are very closely packed to each other, and cannot move here and there, hence, the solids have least kinetic energy.

Hence, the correct option is D.
