MCQ
$K.E.$ of molecular motion appears as:
A
Pressure
B
$P.E.$
✓
Temperature
D
All of the above
✓
Answer
Correct option: C.
Temperature
In the kinetic theory of gasses, increasing the temperature of a gas increases the average kinetic energy of the molecules, causing increased motion. This increased motion increases the outward pressure of the gas, an expected result from the ideal gas equation $\text{PV = NkT}$
Hence, the kinetic energy of the molecular motion appears as temperature since it varies with change in temperature.
