From a physics perspective, what is the most accurate description of the process of cooling?

The addition of a "cold" substance to an object.

The transfer of energy out of a substance.

The molecules stopping their movement completely.

A chemical reaction that absorbs cold particles from the environment.

When a substance is cooled, what is the primary effect on its molecules?

They lose kinetic energy and slow down.

They break their chemical bonds and reform.

They increase in size and mass.

They move farther apart and become more random.

They begin to vibrate more rapidly in fixed positions.

They settle into more stable and orderly patterns.

They attract more molecules from the surrounding environment.

The molecules gain energy from the cold, causing them to expand.

The molecules lose energy to the colder environment, move slower, and get closer together.

The molecules freeze into a solid block of air at the bottom of the balloon.

The number of molecules inside the balloon decreases as they escape through the rubber.
