Two identical containers A and B with frictionless pistons contain the same ideal gas at the same temperature and the same velocity V. The mass of the gas in A is `m_A,` and that in B is `m_B`. The gas in each cylinder is now allowed to expand isothermally to the same final volume 2V. The changes in the pressure in A and B are found to be `DeltaP and 1.5 DeltaP` respectively. Then

`2m_A =3m_8`

`3m_A =2m_8`

`4m_A=9m_8`

`9m_A=4m_8`

Two identical containers A and B have frictionaless pistons. They contain the same volume of an ideal gas at the same temperature. The mass of the gs in A is m_(A) and that B is m_(B) . The gas in each cylinder is now allowed to expand isothermally to double the intial volume. The chages in the pressure in A and B are fopund to be Delta and 1.5Deltap respectively.

At same temperature and pressure of an ideal gas

Two identical containers A and B having volume of ideal gas at the same temperature have mass of the gas as m_(A) and m_(B) respectively. 2 m_(A) = 3 m_(B) . The gas in each cylinder expand isothermally to double its volume. If the change in pressure in A is Delta p , find the change in pressure in B :
