Answer:
When heat is constantly supplied by a burner to boiling water, the temperature of the water does not rise at all. This is because during the process of vaporization, the heat energy supplied is used to convert the liquid water into water vapor rather than increasing the temperature of the water.
Explanation:
When heat is supplied to boiling water, it undergoes the process of vaporization. Vaporization is the phase transition from a liquid to a gas, and it occurs at the boiling point of the substance. In the case of water, the boiling point is 100 degrees Celsius (212 degrees Fahrenheit) at atmospheric pressure.
During the process of vaporization, the heat energy supplied to the water is used to break the intermolecular forces between the water molecules, allowing them to escape into the surrounding air as water vapor. This process requires a large amount of energy, known as the latent heat of vaporization.
As the heat energy is absorbed by the water molecules and used for vaporization, the temperature of the water remains constant at the boiling point. This is because the energy is being used to change the state of the water rather than increase its temperature.
Once all the liquid water has been converted into water vapor, the temperature of the water can start to rise again as the heat energy supplied by the burner is no longer being used for vaporization.

To turn solid ice into liquid water we have to push the water molecules inside further apart and break apart the framework (or crystalline structure) that holds them together. So while ice is melting (during the change of state from solid water to liquid ice) all the heat energy we supply is being used to separate molecules and none is left over for raising the temperature. The heat needed to change a solid into a liquid is called the latent heat of fusion.
