The rms velocity of hydrogen of S.T.P is u ms^(-1)If the gas is heated at constant pressure till its volume is three fold ,what will be its final temperature and rms velocity ?

The rms velocity of hydrogen of S.T.P is u ms^(-1)If the gas is heated

1.	The rms velocity of hydrogen of S.T.P is u ms^(-1)If the gas is heated at constant pressure till its volume is three fold ,what will be its final temperature and rms velocity ?
Answer» SOLUTION :Here `v_1 = u " ms"^(-1) , T_1 = 273K,` `V_1=V("SAY"), V_2=3 V` USING CHARLE's for constant pressure, `V_2/V_1=T_2/T_1` (or) `T_2=V_2/V_1xxT_1` `=(3V)/Vxx273=819K` As`V_2/v_1 sqrt((T_2)/(T_1))` `:.V_2/u=sqrt((819)/273)=sqrt3` (or) `V_2=sqrt3u ms^(-1)`
