2 moles of an ideal monoatomic gas is carried from a state \(\left(p_{0}, V_{0}\right)\) to state \(\left(2 p_{0}, 2 V_{0}\right)\) along a straight line path in a \(p-V\) diagram. The amount of heat absorbed by the gas in the process is given by
- A \(3 p_{0} V_{0}\)
- B \(\frac{9}{2} p_{0} V_{0}\)
- C \(6 p_{0} V_{0}\)
- D \(\frac{3}{2} p_{0} V_{0}\)

Then some amount of another immiscible liquid of density \(\rho_{2}\left(\rho_{2} < \rho_{1}\right)\) is added to the liquid in the container so that the cylinder now floats just fully immersed in the liquids with \(x_{2}\), fraction of volume of the cylinder inside the liquid of density \(\rho_{1}\).
