In figure,the change in internal energy of a gas that is taken from A to C is 800J.The work done along the path ABC is 500J.If the pressure at point A is five times that at point C, what is the work done by the system in going from C to D (path)?

Find the change in internal energy if heat supplied to the gaseous system is 100 J and work done by the system is 80 J.

In the given figure, an ideal gas changes its state from A to C by four paths. The path for which work done is least, is

A sample of an ideal gas is taken through the cyclic process abca and shown in the figure. The change in the internal energy of the gas along the path ca is -180J . The gas absorbs 250J of heat along the path ab and 60 J along the path bc. the work done by the gas along the path abc is:

When a system is taken from A to C through path ABC, 10 J of heat flows to the system and 4 J of work is done by the system. How much heat flows into the system in path ADC, if the work done by the system is 3 J ?

What is the change in internal energy if 10 J of heat is given to system at constant pressure and 20 J of work is done by the system?

For a gaseous system find change in internal energy if the heat supplied to the system is 50 J and work done by the system is 16 J.

For a gaseous system find change in internal energy if the heat supplied to the system is 50 J and work done by the system is 16 J.

If change in internal energy -90 J. The work done by system is + 50 J. Calculate the heat change.

If change in internal energy -80 J. The work done by system is +40 J. Calculate the heat change.

A system has internal energy equal to U_(1), 450J of heat is taken out of it and 600J of work is done on it. The final energy of the system will be
