Question

Identify the change taking place in the following processes.

• A. Irreversible physical change
• B. Reversible chemical change
• C. Reversible physical change
• D. Irreversible chemical change

Answer 1

The correct option is C Reversible physical change

Continuous application of heat to ice will cause the ice to melt into water. Further application of heat will convert the water to steam. However, on cooling, we find that the steam can be converted into water and then into ice. Since we see that there is only a change in the physical state of the water and that this entire process is reversible, this is a reversible physical process.
