An ideal gas is made to undergo a cycle depicted by the PV diagram alongside. The curved line from A to B is an adiabat.

Then-

An ideal gas undergoing adiabatic expansion obeys the relations

An ideal gas is taken around the cycle ABCD shown in the P_V diagram below. The net work done by the gas during the cycle is equal to

An ideal gas is taken around the cycle ABCD shown in the P_V diagram below. The net work done by the gas during the cycle is equal to

A constant amount of an ideal gas undergoes the cyclic process ABCA in the PV diagram shown below The path BC is an isothermal. The work done by the gas during one complete cycle, beginning and ending at A, is nearly-

An ideal gas is made to undergo the cyclic process shown in the figure below. Let /_\W depict the work done, /_\U be the change in internal energy of the gas and Q be the heat added to the gas. sign of each of these three quantities for the whole cycle will be (0 refers to no change)

An ideal monoatomic gas is taken round the cycle ABCD A shown in the PV diagram in the given fig. The work done the cycle is

An ideal gas undergoes a four step cycle as shown in the P-V diagram below. During this cycle heat is absorbed by the gas in

An ideal gas is taken ABCD as shown in the PV diagram. The work done during a cycle is
