An ideal gas undergoes four different processes from the same initial state (figure). Four processes are adiabatic, isothermal, isobaric and isochoric. Out of \(1,\) \(2,\) \(3\) and \(4,\) which one is adiabatic?
1. | \(4\) | 2. | \(3\) |
3. | \(2\) | 4. | \(1\) |
Consider the \((P\text-V)\) diagram for an ideal gas shown in the figure.

(a) | The increase in temperature of an iron rod by hammering it. |
(b) | A gas in a small container at a temperature \(T_1\) is brought in contact with a big reservoir at a higher temperature \(T_2\) which increases the temperature of the gas. |
(c) | A quasi-static isothermal expansion of an ideal gas in a cylinder fitted with a frictionless piston. |
(d) | An ideal gas is enclosed in a piston-cylinder arrangement with adiabatic walls. A weight \(w\) is added to the piston, resulting in the compression of gas. |
