The volume of a gas in a container at a constant temperature varies inversely as the pressure. The volume is 25 cubic centimeter at a pressure of 11 pounds. Use a proportion to find the pressure when the volume is 59 cubic centimeters.

Pressure would be approximately 4.66 pounds.

Step-by-step explanation:

Given:

Volume of gas (V) = 25 cubic cm

Pressure of the  gas (P) = 11 pounds

We need to find the pressure when volume is 59 cubic cm.

Solution:

Now Given:

∝

so we can say that;

where k is a constant.

When V = 25 cubic cm, P =11 pounds.

So the equation becomes as.

Now we need to find the pressure when Volume is 59 cubic cm.

Hence Pressure would be approximately 4.66 pounds.
