Question

At what temperature is the substance a heated gas ?

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

Temperature at below zero degrees represent that the substance is in solid state.

Temperature at zero degree celsius represents that substance starts to melt.

Whereas temperature at 100 degree celsius represents that the substance is changing from liquid to gas.

On the other hand, temperature above 100 degree celsius represents that the  liquid has completely converted into gas.

Thus, we can conclude that above $100^{o}C$ temperature is the substance a heated gas.

Answer 2

Probably, above 100 Degree Celsius.
