STANDARD Physics Gas Laws MCQ Question
Three samples of the same gas A, B and C(γ = 3/2) have equal volume initially. Now, the volume of each sample is doubled. For A, the process is adiabatic; for B, it is isobaric and for C, the process is isothermal. If the final pressure are equal for all the three samples, the ratio of their initial pressures is
2:1:√2
2√2:1:√2
√2:1:2
√2:2:1
Correct Answer
Detailed Explanation
Let be the initial pressures of the three samples. Using the relations for adiabatic, isobaric, and isothermal processes, we find the ratio ensures equal final pressures.
