Question

A bulb 'X' of unknown volume containing a gas at 1 atm pressure is connected to an evacuated bulb of 0.5L capacity through a stop clock the pressure of whole system after sometime was found to have a constant value of 570mm Hg. What is the volume of bulb 'X'.

Answer 1

Answer:

1.5 L is the volume of bulb 'X'.

Explanation:

When the bulbs were disconnected

Volume of bulb X be $V_1$

Pressure of the gas in bulb X ,$P_1= 1 atm$

When the bulbs were connected

New volume of system  be $V_2=V_1+0.5L$

New pressure of the gas in the system ,$P_2= 570 mmHg=0.75 atm$

On applying Boyle's law:

$P_1V_1=P_2V_2$

$1 atm\times V_1=0.75 atm\times (V_1+0.5 L)$

$V_1=1.5 L$

1.5 L is the volume of bulb 'X'.
