Question 242

A solid substance is heated until it turns into a liquid, and then heated further until it becomes a gas. Subsequently, the gas is cooled down back into a liquid. What is the correct order of these changes of state?

A

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

B

melting→condensation→freezing\text{melting} \rightarrow \text{condensation} \rightarrow \text{freezing}melting→condensation→freezing

C

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

D

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