JEE Advanced2007PhysicsKinetic Theory of GasesActual
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.
Options
- AStatement I is true, Statement II is true; Statement II is a correct explanation for Statement I
- BStatement I is true, Statement II is true; Statement II is NOT a correct explanation for Statement I
- CStatement I is true, Statement II is false
- DStatement I is false, Statement II is true
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
Total translational kinetic energy = 3 2 n R T= 3 2 P V=1.5 P ~V Correct option is (b).
