What happens to molecules when the kinetic energy decreases?
Explanation: Kinetic energy of the molecules of a subsance is directly proportional to the temperature of molecule So as the kinetic energy decrease, temperature also decreases.
What is the average kinetic energy of any substance at 0 K?
0 Kelvin is the temperature where the is no kinetic energy, so the answer is 0.

What is the kinetic energy of 1 mole of O2 at 77 C?
Since oxygen is a diatomic gas, its molecules have 5 degrees of freedom. Therefore, the total kinetic energy of molecule of Oxygen is 52kBT.
What temperature is kinetic energy of O2?
Mean kinetic energy of molecule depends upon temperature only. For O 2 it is same as that of H 2 at the same temperature of −73°C.
At what temperature does the average translational kinetic energy?
1). As such, it can be concluded that the average kinetic energy of the molecules in a thermalized sample of gas depends only on the temperature. However, the average speed depends on the molecular mass….27.1: The Average Translational Kinetic Energy of a Gas.
