Question

the pressure of a certain quantity of a gas varies inversely as the volume. when the pressure is 30units, volume is 76units. Find the volume when the pressure is 30.4unit

Answer 1

hope this is your answer

Answer 2

Dear Student,

● Answer -

V = 75 units when P = 30.4 units.

● Explaination -

Given that pressure of a gas varies inversely as the volume.

P ∝ 1/V

P = k/V

k = PV

In first instant, P = 30 units and V = 76 units.

k = 30 × 76

k = 2280 units

Volume when P 30.4 units is -

V = k/P

V = 2280/30.4

V = 75 units

Hence, the volume is 75 units when the pressure is 30.4 units.

Thanks dear. Hope this helps you...
