Question

1
At what temperature, the RMS velocities of hy-
drogen (1 atm. pressure) and oxygen (NTP) will
be same
(A) 37 K
(B) 17 K
(C) 512K
(D) 27 K​

Answer 1

Answer:

Option (B) 17K

Explanation:

At NTP ,

Temperature = 20°C

Pressure ,= 1atm

Given,

Vrms(O2) = Vrms(H2)

→ √3R(273 + 20°C)/32 = √3RT/2

→ √293/32 = √T/2

T ≈ 17K
