Detailed explanation-1: -Yes, the melting of ice cream is a physical change because here only change in physical state is taking place that is from solid to liquid and if we want again a solid ice cream we can freeze it.

Detailed explanation-2: -Essentially, ice cream melts because it absorbs the energy around it in the form of heat. This extra energy causes the atoms to vibrate, turning the solid into a liquid-and eventually into a gas (which is not actually possible on earth outside of lab conditions).

Detailed explanation-3: -A block of ice is solid water. When heat (a form of energy) is added, the ice melts into liquid water. It has reached its melting point – 0°C. Continue to apply heat, and the water will turn into water vapour, which is water in its gaseous state.

Detailed explanation-4: -When the ice cream melts, its delicate molecular structure breaks down, and all those microscopic air bubbles escape. That’s why when you melt and then refreeze ice cream, it’s firmer and a little bit smaller on the second freeze: no air to fluff it up!

Detailed explanation-5: -When ice melts, the resulting water is denser, so a particular mass of what had been solid ice will have a smaller volume when it becomes liquid water. This change in volume exactly offsets the small percentage of ice that is above the water’s surface. Therefore, melting sea ice does not affect sea levels.
