The temperature of a gas is raised from ...

The temperature of a gas is raised from `27 ^@ C` to ` 927^@C` The root mean square speed of the gas

Text Solution

Verified by Experts

The correct Answer is:
2
`d = (pH)/(RT)`
`:. (d_(1))/(d_(2)) = (P_(1))/(T_(1)) xx (T_(2))/(P_(2)) = (P_(1))/(P_(2)) xx (T_(2))/(T_(1)) = (1)/(4) xx (2)/(1) = (1)/(2)`
`d_(2) = 2d_(1)`
