Question
An ideal gas is taken from point A to point C on P-V diagram through two process AOC and ABC as shown in the figure. Process AOC is isothermal
- Process AOC requires more heat than process ABC
- Process ABC requires more heat than process AOC
- Both process AOC & ABC require same amount of heat
- Data is insufficient for comparison of heat requirement for the two processes
The correct answer is: Process AOC requires more heat than process ABC

An ideal gas is trapped inside a test tube of cross-sectional area 20 × 10–6 m2 as shown in the figure. The gas occupies a height L1 at the bottom of the tube and is separated from air at atmospheric pressure by a mercury column of mass 0.002 kg If the tube is quickly turned isothermally upside down so that mercury column encloses the gas from below The gas now occupies height L1 in the tube. The ratio is [Take atmospheric pressure = 105 Nm–2]
