Question

At a constant temperature volume of a gas was found to be 300cm^3 at a pressure of 760 mm hg if the pressure of the gas is increased by 10%find the new volume

Answer 1

where,

P_1\text{ and }V_1 are initial pressure and volume.

P_2\text{ and }V_2 are final pressure and volume.

We are given:

P_1=760 mmHg\V_1=400cm^3\P_2=760+\frac{25}{100}\times 760=950mmHg\V_2=?

Putting values in above equation, we get:

760\times 400=950\times V_2\\V_2=320cm^3

Thus the new volume will be 320cm
