Question

Which statement describes the motion of the molecules within water when enough heat energy is added to boil the carpet cleaner?

A The molecules stop moving.
B The molecules move more slowly.
C The molecules move more quickly.
D The molecules begin moving at a constant rate.

Answer 1

When enough heat energy is added to boil the carpet cleaner, the molecules within water move more quickly. The transition from a liquid to a gas occurs when the molecules have enough energy to overcome the attractive forces holding them together, which is why the water boils.

Step-by-step explanation:

When enough heat energy is added to boil the carpet cleaner, the motion of the molecules within water will C) move more quickly. In the context of molecular motion, temperature and molecular movement are closely linked. As temperature increases, so does the kinetic energy of the molecules, leading to faster movement. This principle is reflected in the process of boiling water, where the addition of heat raises the temperature and thus speeds up the molecular motion until the water turns into steam.

As heat energy is added to water, the molecules gain kinetic energy, causing them to move faster.

The transition from a liquid to a gas occurs when the molecules have enough energy to overcome the attractive forces holding them together, which is why the water boils.
