Question

At a constant temperature, gas occupies volume of 200 ml.At a pressure of0 720 bar. It is subjected to external
0.900 bar. what is resulting volume of the gas? (Hint: Boyles law)​

Answer 1

Answer:

160

Explanation:

Given At a constant temperature, gas occupies volume of 200 ml at a pressure of 0.720 bar. It is subjected to an external  pressure of 0.900 bar. what is resulting volume of the gas?

By using Boyle’s law we get

P1V1 = p2V2

P1 = 0.72 bar, V1 = 200 ml, p2 = 0.9 bar

We need to find V2

So V2 = P1V1 / P2

         = 0.72 x 200 / 0.9

V2 = 160 ml
