Two glass bulbs A and B are connected by a very small tube having a stop-cock. Bulb A has a volume of 100 $c m^{3}$ and contained the gas; while bulb B was empty. On opening the stop-cock, the pressure fell down to 40%. The volume of the bulb B must be

Options:

Answer:

Solution:

$P_{1} = 1 atm$

$P_{2} = 1 atm \times \frac{40}{100} = 0.40 atm$

$V_{1} = 100 c m^{3}$

$V_{2} = ?$

At constant temperature, $P_{1} V_{1} = P_{2} V_{2}$

So $V_{2} = \frac{P_{1} V_{1}}{P_{2}}$

$- \frac{1 atm \times 100 c m^{3}}{0.40 atm}$

$= 250 c m^{3}$

Hence, the volume of bulb $B = (250 - 100) {cm}^{3}$

$= 150 {cm}^{3}$
