pressure increase hard

Question

At constant temperature, pressure increase in ideal gas container implies average molecular kinetic energy:

RankGuru · Accepted Answer

The Kinetic Theory of Gases explicitly states that the average translational kinetic energy of a molecule is **solely a function of temperature**: $\bar{K} = \frac{3}{2} k_B T$. 
- If the temperature is constant, $\bar{K}$ remains the same.
- A pressure increase at constant $T$ must be caused by an increase in number density ($N/V$, i.e., compression), not by the individual molecules hitting the walls harder on average.
