Question: The average kinetic energy of gas molecules is proportional to which of the following?

Options:

Correct Answer: Temperature

Solution:

The average kinetic energy of gas molecules is directly proportional to the absolute temperature of the gas.

The average kinetic energy of gas molecules is proportional to which of the following?

The average kinetic energy of gas molecules is proportional to which of the following?

Step 1: Understand what kinetic energy is. Kinetic energy is the energy that an object has due to its motion.
Step 2: Know that gas molecules are always moving. The speed of these molecules relates to their kinetic energy.
Step 3: Learn about temperature. Temperature is a measure of how hot or cold something is, and it relates to the energy of the molecules in a substance.
Step 4: Recognize that absolute temperature is measured in Kelvin. It starts from absolute zero, where all molecular motion stops.
Step 5: Understand the relationship: As the absolute temperature of a gas increases, the average kinetic energy of its molecules also increases.
Step 6: Conclude that the average kinetic energy of gas molecules is directly proportional to the absolute temperature of the gas.

Kinetic Energy and Temperature – The average kinetic energy of gas molecules increases with an increase in absolute temperature, as described by the equation KE = (3/2)kT, where k is the Boltzmann constant and T is the absolute temperature.
