MHT CET 2024 Physics question
The r. m. s. velocity of hydrogen at S. T. P is 'u' . If the gas is heated at constant pressure till its volume becomes three times, then the final temperature of the gas and the r. m. s. speed are respectively
Answer: (A)
Solution
At S.T.P. the temperature is K. At constant pressure Charles' law gives , so K. The r.m.s. speed depends on temperature as , so $ =
