(B) More
(C) Same
(D) Can’t say

Answer 1

Particle energy is the kinetic and potential energy of a particle. All the particles are having some energy, the highest energy are of the gases and the lowest are of the solids and the liquids are having energy lower than the gases and higher than the solids.

Complete step-by-step answer
We will start with the definition of particle energy:
Particle energy: The particle having the kinetic and potential energy is called the particle energy. Now, we compare the particle energies of the different states of matters,
The energy of a particle varies as the temperature depends on the sample of matter.
Now, talking all the states of matter one-by-one:
Solids: The solids are having lowest particle energy, because of its stable volume, mass and shape and having the highest force of attraction between the constituents.
Liquids: The liquids are having particle energy lower than the gases and higher than that of the solids, because of its force of attraction is lower than solids and higher than the gases and also the stability.
Gases: The gases have the highest particle energy, because of its un-stability, having no fixed volume, mass and shape and the force of attraction between the constituents are lowest.
So, from the above discussion,
The one particle is at liquid state and another is at solid state, so, the particle energy of the liquid will be higher than that of the solid.
So, particles in water are having more energy as compared to particles in ice.
Hence, the correct option is (B).

Note:
The particle when changed from liquid to gas or solid to liquid its particle energy increases and when the particle changes from gas to liquid or liquid to solid, the particle energy decreases as achieving higher stability.
