AP EAMCET · PHYSICS · Kinetic Theory of Gases
A light container having a diatomic gas enclosed within is moving with velocity \(v\). Mass of the gas is \(M\) and number of moles is \(n\). The kinetic energy of gas w.r.t. ground is
- A \(\frac{1}{2} M^2+\frac{3}{2} n R T\)
- B \(\frac{1}{2} M v^2\)
- C \(\frac{1}{2} M^2+\frac{5}{2} n R T\)
- D \(\frac{5}{2} n R T\)
Answer & Solution
Correct Answer
(C) \(\frac{1}{2} M^2+\frac{5}{2} n R T\)
Step-by-step Solution
Detailed explanation
According to kinetic theory of gases, Energy of diatomic gas having \(f\) number of degree of freedom is given as, \[ B_1=n \frac{f}{2} R T \quad \text { [For nmole gas] } \] Since, degree of freedom of a diatomic gas, \[ f=5 \] \(\therefore\) Kinetic energy of diatomic gas with…
