Question

Consider the arrangement of bulbs shown below
what is the pressure of system when all the stopcocks are opened ​

Answer 1

Answer:

If T is constant then the PV product is constant

$P_{1} V_{1} +P_{2} V_{2} +P_{3} V_{3} =P_{4} V_{4}$

Here 4 is the combination of all 3 bulbs

The combined volume=2.5L=$V_{4}$

(635)(1)+(212)(1)+(418)(0.5)=($P_{4}$)(2.5)

$P_{4} =422.4mm$

Answer 2

Answer:

hey you can solve this by using

PV=nRT

BTW MY best friend name is also ayushi.......
