Define the internal energy of the system

In a thermodynamic process, pressure of a fixed mass of a gas is changed in such a manner that the gas releases 30 J of heat and 10 J of work is done on the gas. If the initial internal energy of the gas was 30 J , then the final internal energy will be

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 ?

Should the internal energy of a system necessarily increase if heat is added to it?

In thermodynamic process, pressure of a fixed mass of a gas is changes in such a manner that the gas molecules gives out 20 J of heat and 10 J of work is done in the gas. If the initial internal energy of the gas was 40 J , then the final internal energy will be
