Question

The temperature in a beaker of water is 50 degrees Celsius. Kiley puts the water into a freezer. After a few minutes, she measures the temperature again. It is now 10 degrees Celsius. How did the water particles change

Answer 1

Answer:

This question lacks options; the options are:

A) They moved more freely

B) They moved closer together.

C) The average speed increased.

D) The average kinetic energy increased

The answer is B

Explanation:

The water in the beaker is described to be in a liquid state of matter. Its temperature decreases from 50°C to 10°C when placed in a freezer by Kiley. This means that heat is gradually being lost as the liquid water undergoes freezing into a solid state.

When water in a liquid state is freezed, it's molecules, which were moving more freely begin to move closer together because the speed at which the particles in the liquid state moved has been reduced.
