The temperature of 1 mol of an ideal mon...

The temperature of 1 mol of an ideal monoatomic gas at constant pressure of 1 atm changes from `25^(@)C and 50^(@)C`. Calculate `Delta U and Delta H` in this process, `(C_(V)=(3)/(2)R)`.

Text Solution

Verified by Experts

`Delta H= nC_(P)(T_(2)-T_(1))= 1 xx(5)/(2)R(232-298) K`
`= 1 xx(5)/(2)xx8.314xx25 J= 519.63 J`
`Delta H= Delta U + nRDelta T or , 519.63= Delta U + 1xx8.314xx25`
`therefore Delta U= 311.78 J`
