Question

K.E. of molecular motion appears as:

• A. Pressure
• B. P.E.
• C. Temperature
• D. All of the above

Answer 1

Answer: (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 $PV=NkT$

Hence, the kinetic energy of the molecular motion appears as temperature since it varies with change in temperature.

Hence, the correct option is $C$
