Molecular kinetic energy, expressed in terms of absolute temperature (T), is directly proportional to________________?
Show answer Hide answer
Answer: A. T
Explanation
Kinetic theory establishes that temperature is a measure of average molecular energy. The mathematical formula confirms kinetic energy scales linearly with absolute temperature. Doubling the absolute temperature results in a direct doubling of molecular energy. Absolute temperature is measured in Kelvin starting from absolute zero condition. Gas molecules possess random translational kinetic energy in continuous motion. Boltzmann constant relates individual molecular energy to macroscopic temperature scales.
This relationship explains why gas pressure increases when a container is heated. Meteorologists use this principle to understand atmospheric behavior across temperature gradients. Cryogenic research relies on this proportionality to study matter near absolute zero. Option B represents a mechanical work or joule conversion constant symbol. Option C introduces a squared term which contradicts the linear temperature relation. Options D and E refer to velocity ratios rather than absolute temperature.
