Question 84

A substance starting as a solid is heated. It first changes state to a liquid, and then with continued heating, it becomes a gas.

The gas is then cooled and changes back into a liquid.

What is the correct order of changes of state for this substance during these processes?

A

melting→vaporisation→condensation\text{melting} \to \text{vaporisation} \to \text{condensation}melting→vaporisation→condensation

B

melting→condensation→vaporisation\text{melting} \to \text{condensation} \to \text{vaporisation}melting→condensation→vaporisation

C

freezing→vaporisation→condensation\text{freezing} \to \text{vaporisation} \to \text{condensation}freezing→vaporisation→condensation

D

melting→sublimation→condensation\text{melting} \to \text{sublimation} \to \text{condensation}melting→sublimation→condensation
