Question

What changes occur at the molecular level when ice cream melts and forms a liquid?

Answer 1

Explanation:

It is known that before melting ice cream is present in a solid state so, its molecules are much closer due to which it has retained its shape.

But as its molecules absorb energy from the surroundings the they tend to gain kinetic energy. Due to this there will be increase in collision between its particles and they will move apart from each other. As a result, ice cream will start to melt.

Therefore, when ice cream melts and forms a liquid then molecules move away from each other at the molecular level.

Answer 2

When ice cream melts from solid to liquid, the motion of the molecules increases. This is because as the phase change moves from solid to liquid to gas, entropy increases which increases the probability of the molecules to collide and move in the system. This increase may be because of the increase in temp, probable cause of the melting of icecream.
