Question

unit exam: thermal energy and earths processes a student conducted an experiment to study heat transfer in a sealed, insulated container filled with water. the student applied heat continuously. however, after a certain point, the temperature of the water stopped increasing. what is the most likely reason for this observation? the water absorbed all the thermal energy possible the heating source is not supplying enough heat the water has completely turned into vapor the water is now boiling and changing state

Explanation:

When water is heated, its temperature rises until it reaches its boiling - point. At the boiling - point, the heat energy is used for the phase change from liquid to gas (vapor) rather than increasing the temperature. This is called latent heat of vaporization. In a sealed, insulated container, when the water starts boiling, the temperature remains constant as long as the phase change is ongoing.

Answer:

The water is now boiling and changing state.
