How does increasing the temperature affect the movement of gas molecules?

Increasing the temperature of a gas directly correlates with the kinetic energy of its molecules. As the temperature rises, the average kinetic energy of the gas molecules also increases, leading to more vigorous movement. This is based on the kinetic molecular theory of gases, which asserts that gas molecules are in constant motion and that their speed is influenced by temperature.

When the temperature increases, the energy provided to the gas molecules allows them to overcome intermolecular forces more effectively and move more rapidly. This increased movement results in a higher frequency of collisions among the molecules and with the walls of their container, which can also lead to an increase in pressure if the volume remains constant.

In summary, as the temperature of a gas rises, the molecules gain kinetic energy and thus move faster, which is accurately represented by the selected answer.
