In a thermodynamic process, pressure of ...

In a thermodynamic process, pressure of a fixed mass of a gas is changed in such a manner that the gas releases `20` `J` of heat and `8` `J` of work is done on the gas. If the initial internal energy of the gas was `30` `J`, what will be the final internal energy ?

`42` `J`

`12` `J`

`10` `J`

`18` `J`
