Question

The pressure of an ideal gas is written as $$P=\dfrac {2E}{3V}$$. Here $$E$$ stands for


A
total translational kinetic energy
loader
B
rotational kinetic energy
loader
C
average translation kinetic energy
loader
D
total kinetic energy
loader

Solution

The correct option is A total translational kinetic energy
Given $$P=\dfrac{2E}{3V}$$
$$\Rightarrow PV=\dfrac{2}{3}E$$
$$\Rightarrow nRT=\dfrac{2}{3}E$$        $$\left\{ as\;PV=nRT\;ideal\;gas\;equation \right\} $$
$$\Rightarrow\dfrac{3}{2}nRT=E$$
$$\Rightarrow \dfrac{3}{2}KT=E$$           $$\left\{K=nR\right\}$$
According to law of equipartition of energy it has $$3$$ degree of freedon thus it is translation kinetic energy.
Hence, the answer is total translational kinetic energy.
