A sample of gas is going through cyclic process, work-done by gas is

Three moles of an ideal gas undergo a cyclic process shown in figure. The work done by the gas during the process is

A monoatomic gas (one mole) is taken through process $A\to B$ as shown in figure. Find average molar heat capacity for the process.

Consider the $P-V$ diagram shown in figure, value of work done by gas is given by

Find net work done by gas in the cyclic process $A\to B\to D\to E\to A$

An ideal monatomic gas undergoes process $A\to B\to C$ as shown. Find efficiency of the thermodynamic cyclic shown in figure.
