The volume V of a gas varies inversely as the pressure P upon it. The volume of a gas is 200 cu cm under a pressure of 32kg/sq. cm
a. find the variation constant
b. what will be its volume under a presure of 40 kg/sq. cm
I think Jhevon should have wrote it as:
Where is the volume and the pressure.
In the first question, to find the constant you need to put the given values for and in the equation, and solve for .
In the second question you now make use of that value for when solving for the volume, .
