Show adiabatic and isothermal processes on a single P-V diagram.

Is isothermal process slow or fast?

The reversible expansion of an ideal gas under adiabatic and isothermal conditions is shown in the figure. Which of the following statement(s) is (are) correct ?

One mole of a van der Waals' gas obeying the equation (P + a/(V^2)) (V - b) = RT undergoes the quasi-static cyclic process which is shown in the P-V diagram. The net heat absorbed by the gas in this process is

A 1.0 mol of ideal gas, initially at 10 atm and 300 K Is allowed to expand isothermally to 1.0 aim. as follows : Inversible expansion against 1.0 atm Determine the net work done by the system and describe the whole processes on p-V diagram.

An ideal gas undergoes four processes: isochoric, isobaric, isothermal and adiabatic. In which process is (i) the change in internal energy zero?

For adiabatic process, which is correct-

According to the first law of thermodynamics, DeltaU=q+w . Write down the form of this equation for the following process: (i) cyclic process (ii) adiabatic process (iii) isothermal expansion of an ideal gas (iv) process occurring in an isolated system.
