Solve the problem. The volume V of a gas varies inversely as the pressure P on it. The volume of a gas is 240 cm3 under a pressure of 23 kg/cm2 What will be its volume under a pressure of 30 kg/cm2?

In this situation, because of the inverse proportionality,

P1/P2 = V2/V1

1 and 2 denote the two different conditions.

23/30 = V2/240

Solve for V2, the volume at P2 = 30

however, the options are:

184, 166, 313, or 297

I got 313, is this correct?

(240*30)/23=313

No, it is 184. You incorrectly rearranged the equation I wrote.

The volume has to decrease when you increase the pressure.
