Question

Melting of ice is a physical change or chemical change?

Answer 1

Physical change:

• Physical change is known as the change in which the arrangement of molecules gets altered which brings the change in the state but there are no new products gets formed, hence the molecular makeup remains unchanged.
• When a physical change occurs, no energy changes occur as the amount of energy required to bring about a physical change is the same as the amount of energy required to reverse it.
• The changes are reversible and only last for a short time.

Melting of ice:

• Melting ice is known as a physical change as it only involves a change in the physical state of water, from ice to water in the liquid state.
• Furthermore, no new chemical substances are created, and hence the molecular composition of ice and water remains unaffected.
• Also, here the transformation is reversible as freezing water will turn it back into ice which was its initial state.

Hence, the Melting of ice is a physical change.
