The molecules of a given mass of a gas have arms velocity of 200 m/sec at 27 0 C and 
pressure. When the temperature is 127°C and pressure is 
, the rms velocity in m/sec will be
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
C
Change in pressure will not affect the rms velocity of molecules. So we will calculate only the effect of temperature.
As 
∴ ∴ 
⇒ ⇒ 
⇒ ⇒ 
.
