Statement -1 : When temperature is incrteased, viscosity of the gas decreases.
Statement -2 : With the increase in temperature, the gas becomes lighter.

A

Statement -1 is true , Statement -2 is true , Statement -2 is a correct explanation of Statement -1.

B

Statement -1 is true , Statement -2 is true , Statement -2 is not a correct explanation of Statement -1.

C

Statement -1 is true, Statement -2 is false.

D

Statement -1 is false , Statement -2 is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Here, statement - 1 is wrong because the viscosity of a gas increases with increase in temperature as `eta prop sqrt(T)` . The statement - 2 is correct.
