Internal energy is a state function. So for an cyclic process it is zero.

Change in the state variable in a cyclic path is zero.

Parthi said: (Oct 12, 2015)  
Energy is change the way a cyclic path is zero.

There will be no in internal energy when a system is in cyclic process.

Is the work done in a cyclic process is zero? how?

Manjit Gangwar said: (Oct 6, 2018)  
In a cyclic process, the system returns in its initial state so that on the change in internal energy.

Ist law. : heat added to the system is equal to work done by the system.
