An Ideal Monatomic Gas Originally in State a Is Taken

Multiple Choice

An ideal monatomic gas originally in state A is taken reversibly to state B along the straight-line path shown in the pressure-volume graph.

-Suppose that the same gas is originally in state A as described above,but its volume is increased isothermally until a new volume of 3.0 liters is reached.Which one of the following statements for this isothermal process is false?

A) The change in the internal energy is zero.
B) The final state of the system will still be B.
C) The work done will be smaller for the isothermal process.
D) The heat added will be smaller for the isothermal process.
E) The heat added for the isothermal process will be equal to the work done.
