At absolute zero, the kinetic energy of gas molecules is:

At absolute zero, the kinetic energy of gas molecules is:

Step 1: Understand what absolute zero means. Absolute zero is the lowest possible temperature, which is 0 Kelvin or -273.15 degrees Celsius.
Step 2: Know that kinetic energy is the energy of motion. Gas molecules are always moving, and their movement gives them kinetic energy.
Step 3: Realize that as temperature decreases, the movement of gas molecules slows down.
Step 4: At absolute zero, the temperature is so low that gas molecules stop moving completely.
Step 5: Since the molecules are not moving at absolute zero, their kinetic energy is zero.

Kinetic Energy at Absolute Zero – At absolute zero (0 Kelvin), the motion of gas molecules theoretically comes to a complete stop, resulting in zero kinetic energy.
