Two gases occupy two containers

\mathrm{A}

and

\mathrm{B}

the gas in

\mathrm{A}

, of volume

0.10 \mathrm{~m}^3

, exerts a pressure of

1.40 \mathrm{MPa}

and that in

\mathrm{B}

of volume

0.15 \mathrm{~m}^3

exerts a pressure

0.7 \mathrm{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

\mathrm{MPa}

)

View answer and explanation

Correct option: B

0.98

Option B (0.98 MPa) is correct because the final pressure is calculated using Boyle's law, considering the combined volume and constant temperature.

Assertion: The pressure exerted by an enclosed ideal gas does not depend on the shape of the container.
Reason: The pressure of an ideal gas depends on the number moles, temperature and volume of the enclosed If
