Q3 of 27 Page 83

Consider P-V diagram for an ideal gas shown in Fig 12.2.


Out of the following diagrams (Fig. 12.3), which represents the T-P diagram?



It is given PV= constant

which states that the process is isothermal process. From the graph, we can see that in process 1 & 2 temperature


is constant and the gas expands, while pressure decreases


i.e., P2<P1


∴ graph (iii) represents the correct T-P graph.


option (c) is correct.

An ideal gas undergoes four different processes from the same initial state (Fig. 12.1). Four processes are adiabatic, isothermal, isobaric and isochoric. Out of 1, 2, 3 and 4 which one is adiabatic.

If an average person jogs, she produces 14.5 × 103 Cal/min. This is removed by the evaporation of sweat. The amount of sweat evaporated per minute (assuming 1 kg requires 580 × 103 Cal for evaporation) is

An ideal gas undergoes cyclic process ABCDA as shown in given P-V diagram (Fig. 12.4).

The amount of work done by the gas is

Consider two containers A and B containing identical gases at the same pressure, volume and temperature. The gas in container A is compressed to half of its original volume isothermally while the gas in container B is compressed to half of its original value adiabatically. The ratio of final pressure of gas in B to that of gas in A is
