Question

The temperature of a gas is doubled (1) on absolute scale (2) on centigrade scale. The increase in root mean square velocity of gas will be more in case .............(1/2)

• A. 1

Answer 1

The correct option is A 1
As, $u_{r}ms=\sqrt{3RT/M}$ & $T\left(K\right)=273.15+T\left(C\right)$.
So the increase in root mean square velocity of gas will be more in case 1.
so answer is 1.
