The temperature of a gas is doubled (i) on absolute scale (ii) on centigrade scale. The increase in root mean square velocity of gas will be

Options

A. More in case(i)
B. More in case(ii)
C. Same in both case
D. Information not sufficient

Answer

A

Explanation

T = Temperature in centigrade scale
K = temperature in absolute scale
T = k - 273 `rarr` 2T = 2K - 273 `xx`2
so final temperature in caswe I = 2K
So final temper IN case = 2K - 273
Hence more in case I
