Question

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 temperature of a liquid is always the temperature of the gas above it.

The temperature of a substance does not change during a phase change.

The temperature of a liquid is always 100°C.

The third statement is correct. The temperature of boiling water on a stove will remain at 100°C, even if it has been boiling for an extended period of time. This is because the temperature of a liquid during boiling remains constant, as long as the pressure remains constant as well. At sea level, the pressure is typically constant, and the boiling point of water is 100°C. Therefore, the water will continue to boil at this temperature until all the liquid has turned into gas.
