Thermodynamics - Internal Energy

How many of the following variable can be used to specify the state of the system. Internal energy, composition, pressure, Temperature, Volume, Work

Statement I: When an ideal gas is taken from a given thermodynamics state A to another given thermodynamic state B by any polytropic process, the change in the internal energy of the system will be the same in all processes. Statement II: Internal energy of the gas depends only upon its absolute tmeperature.

In the adjoined figure the indicator diagram of an ideal thermodynamic gas system is represented. If the change in internal energy along the path acb is 10 calorie then change in internal energy along the path bda will be

In a thermodynamic system working substance is ideal gas, its internal energy is in the form of

We consider a thermodynamic system. If DeltaU represents the increase in its internal energy and W the work done by the system, which of the following statements is true?
