Question

Two gases occupy two containers A and B. The gas in A, of volume 0.10 m³, exerts a pressure of 1.40 MPa and that in B of volume 0.15 m³ exerts a pressure of 0.7 MPa. The two containers are united by a tube of negligible volume and the gases are allowed to intermingle. Then if the temperature remains constant, the final pressure in the container will be (in MPa)

• A. 0.70
• B. 0.98
• C. 1.40
• D. 2.10

Hint:

For constant temperature, the pressure and volume of a gas are inversely proportional, as given by Boyle’s Law.
