Two identical gas samples are initially at same temperature and pressure. They are separatly taken into two cylinders of volume V (each) and are compressed to volume V/2 One isothermally and other adiabatically. If final pressures in the process are p_1 and p_2 , then the ratio of p_1//p_2 is

Two identical vessels A and B with frictionless pistons contain the same ideal gas at the same temperature and the same volume V. The masses of gaş in A and B are m_(A) and m_(B) respectively. The gases are allowed to expand isothermally to the same final volume 2 V. The change in pressures of the gas in A and B are found to be Deltap and 1.5 Deltap respectively. Then
