Question

At what temperature will the root mean square velocity of methane becomes double its value at NTP

Answer 1

Answer:

Vrms=[3RT/M]^1/2

So, Vrms is proportional to T^1/2

Ratio of Vrms = 2/1

Normal temperature(T)=293.15K

So,(T'/T)^1/2=2/1

By squaring both sides,

T'=4T

T'=1172.6K

Hope it helps.
