Are the molecules moving faster in a glass of water steam ice

Molecules are moving faster in the glass of Steam.

Explanation:

The three physical states of H₂O are Ice (Solid state), Water (Liquid state) and Steam (Gas state) respectively.

As we know the particles (i. e. molecules) in solid state are stationary and they are unable to change their position and are only vibrating therefore we can omit the option of Ice.

When heat is provided to Ice it melts into liquid water. The molecules are still interacting via intermolecular forces. In this state the molecules are not stationary. They exist in the form of layers (due to intermolecular forces) and these layers slide over each other hence, resulting in the change of position of molecules.

While, when liquid water is further heated it converts into steam (a gas sate). In this state the molecules are not interacting with each other. They move faster in random directions and collide with each other. Hence, this is the correct answer.
