Question

31. At T kelvin and a pressure of a P atm, certain
gas is present in a vessel. If the vessel is
divided into two equal compartments by a
partition, the pressure in each compartment is
1) 4P atm
2) P atm
3) P/4 atm
4) 2 P atm​

Answer 1

Answer:

option 2 is correct

Explanation:

Before removing partition we have to consider some points$\frac{1}{2} *1L$

$V_{H_{2} }$=$\frac{1}{2} *1L$

                               =0.5L

$V_{CH_{4} }$=$\frac{1}{2} *1L$

                                  =0.5L

V=1L

$P_{CH_{4} } =P_{H_{2} } =\frac{P}{2}$

$P_{Tot} =\frac{P}{2} +\frac{P}{2}$

$P_{Tot} =P$

so option 2 is correct
