Question

The atoms and molecules in a gas are in constant motion. Temperature is a measure of their speed as they move. How are these related?

a. As temperature decreases, the molecules and atoms move faster.

b. As temperature increases, the atoms and molecules move more slowly.

c. As temperature increases, the molecules and atoms move faster.

d. Atoms and molecules always move at the same speed regardless of any temperature change.

Answer 1

The answer is C because as you add heat, the atoms grow in energy. See the law of conservation of energy states that energy is neither created nor destroyed. This means energy is being added, or converted, in the form of adding heat, increasing the speed of the molecules. This also explains the change from state to state.
