Question

The kinetic energy of any gas molecule at $0^{\circ }C$ is:

• A. zero
• B. $3408J$
• C. $2cal$
• D. $5.66\times {10}^{-21}J$

Answer 1

The correct option is D $5.66\times {10}^{-21}J$

The kinetic energy of any gas molecule at 0 deg C is $\frac{3}{2}kT=\frac{3}{2}\times 1.38\times {10}^{-23}J/K\times (0+273)K=5.66\times {10}^{-21}J$
