The figure below is a PV diagram for an ideal gas. Process II occurs at constant temperature. In process III, $90$ J of heat is removed from the gas and $34$ J of work is done on the gas.

A$.)$ Find the change in internal energy for process III.

B$.)$ Find $Q,U,$ and $W$ for process I.

$Q=q,$

$U=$

$w=$
