Question

at what temperature will the rms velocity of hydrogen be double its value at stp when pressure remains constant

Answer 1

The Temp at which the rms velocity will be double will be 1092 K or 819 °C

Explanation :

We know that the rms velocity of a gas is directly proportional to the square root of the temperature,

C ∝ √T

temp at stp = T₁ = 273

Temp at which the rms velocity will be double = T₂

=> C₂/C₁ = √(T₂/T₁)

From the given condition,

√(T₂/T₁) = 2

=> T₂/T₁ = 4

=>  T₂ = 4 x 273 = 1092 K = 1092 - 273 = 819 °C

Hence the Temp at which the rms velocity will be double will be 1092 K or 819 °C
