What are isobaric, isochoric, isothermal and adiabatic processes?

Define an adiabatic process.

What do you mean by isothermal and adiabatic processes?

What is Isobar?

Which is true for adiabatic process —

Give two points on comparison between isothermal and adiabatic processes.

What are diathermal and adiabatic boundaries?

The initial state of 1 mol of an ideal gas is (P_(1),V_(1),T_(1)) . The gas is expanded by a reversible isothermal process and also by a reversible adiabatic process separately. If final volume of the gas is same in both the processes, and changes in internal energy in the isothermal and adiabatic processes are DeltaU_(1) and DeltaU_(2) respectively, then-
