Question

explain what happens with the water molecules when you heat up a pot of water until it boils. be sure to use the terms kinetic energy, liquid, gas, and boiling point in your answer. (4 points)

Explanation:

When heat is applied to a pot of water, the water molecules absorb the heat energy. This increases their kinetic energy, causing them to move more rapidly. As the temperature rises, the water remains in the liquid state until it reaches its boiling point (100°C at standard atmospheric pressure). At the boiling point, the kinetic energy of the water molecules is high enough to overcome the intermolecular forces holding them together in the liquid state. The water then undergoes a phase - change from liquid to gas (water vapor), a process called boiling.

Answer:

When a pot of water is heated, the water molecules absorb heat energy, increasing their kinetic energy. They move faster. The water stays as a liquid until it reaches the boiling point. At the boiling point, the high - kinetic - energy water molecules overcome intermolecular forces and change from liquid to gas (water vapor).
