Why does boiling water in a large pot on a stove have a temperature of 100°C even if it has been boiling for an hour? The temper

ature of a liquid is always the temperature of the gas above it. The temperature of a liquid is always 100°C. The temperature of a substance does not change during a phase change.

Answer: Option (c) is the correct answer.

Explanation:

Latent heat of vaporization is defined as amount of heat necessary for a unit mass of a liquid to change into vapor state without any change in its temperature.

So, when we boil water in a large pot at 100 degree celsius then its temperature will remain the same unless and until all the bonds between water molecules are broken down.

Temperature of water in this situation will start to change the moment vapors start to form.

Thus, we can conclude that boiling water in a large pot on a stove have a temperature of 100°C even if it has been boiling for an hour because the temperature of a substance does not change during a phase change.
