Which contains the particles that are vibrating fastest?

boiling water
frozen water
room-temperature water
cold tap water

Option (a) is the correct answer.

Explanation:

When water is boiled then due to the heat provided vibration between the particles increases. As a result, there will be increase in kinetic energy of particles.

Hence, vibration between the particles of boiling water will be the fastest.

Whereas vibration of particles in frozen water, room temperature water and cold tap water will not be the fastest.
