MHT CET 2026 Physics question
The r.m.s. speed of hydrogen at S.T.P. is 'u' m/s. If the gas is heated at constant pressure till its volume becomes three times, the final temperature of the gas and the r.m.s. speed are respectively
Answer: (C)
Solution
At S.T.P. . At constant pressure , so tripling the volume triples the absolute temperature: . The r.m.s. speed , so .
