Boiling water remains at a constant temperature, even if heat energy is being added to it. What happens to the thermal energy of boiling water? (1 point)
Responses
Thermal energy is increasing because liquid is turning into gas, which increases kinetic energy.

The correct response is "Thermal energy remains constant because the temperature does not change."
The correct answer is: Thermal energy remains constant because the temperature does not change.
When water is boiling, heat energy is being constantly added to the system, causing the liquid water to change phase and turn into gas (water vapor). However, even though heat is being added, the temperature of the boiling water remains constant at the boiling point of water (100 degrees Celsius or 212 degrees Fahrenheit at standard atmospheric pressure).
During the boiling process, the thermal energy of the water is being used to break the intermolecular bonds between water molecules, allowing them to escape as gas. This energy transfer is known as latent heat. As long as there is liquid water remaining, the temperature of the water will not rise because the added heat energy is being used to convert it into gas instead of increasing its kinetic energy. Once all the liquid water has been converted into gas, any additional heat energy added will cause an increase in the temperature of the gas.
So, in summary, the thermal energy of boiling water remains constant because the temperature does not change.
