When one mole of monoatomic ideal gas at T temperature undergoes adiabatic change under a constant external pressure of 1 atm, change in volume is from 1 L to 2L. The final temperature in kelvin would be

Answer»

`(T)/(2^((2//3)))`
`T+(2)/(3xx0.0821)`
`T`
`T-(2)/(3xx0.0821)`

SOLUTION :`(T)/(T_("FINAL"))=((V_(2))/(V_(1)))^(gamma-1)=((2)/(1))^((5//3-1))`
`=2^((2//3)),T_("final")=(T)/(2^((2//3)))`
