Statement I The total translational kinetic energy of all the molecules of a given mass of an ideal gas is \(1.5\) times the product of its pressure and its volume.
Statement II The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.
- A Statement I is true, Statement II is true; Statement II is a correct explanation for Statement I
- B Statement I is true, Statement II is true; Statement II is NOT a correct explanation for Statement I
- C Statement I is true, Statement II is false
- D Statement I is false, Statement II is true
Answer & Solution
Correct Answer
(B) Statement I is true, Statement II is true; Statement II is NOT a correct explanation for Statement I
Step-by-step Solution
Detailed explanation
Total translational kinetic energy \(=\frac{3}{2} n R T=\frac{3}{2} P V=1.5 P \mathrm{~V}\)
\(\therefore\) Correct option is (b).
\(\therefore\) Correct option is (b).
