10.The volume V of a given mass of gas varies inversely as the pressure P. When V =2m3 ,P=500 N/m2 .Find the volume when the pressure is 400N/m2 Find the pressure when the volume is 5 m3

.

Step-by-step explanation:

Let and denote the volume and pressure of this gas before the change. Let and denote the pressure of this gas after the change.

The ratio between the volume of this gas before and after the change would thus be .

The ratio between the pressure of this gas before and after this change would be .

Because the volume of a given mass of (ideal) gas varies inversely with pressure, these two ratios should be reciprocal of each other. That is:

.

In other words:

.

Rearrange and solve for , the volume of this gas after the change:

.

.

From the question:

Solve for :
