Question 43365
The volume V as a mass of gas varies directly as the temperature T and inversly as the pressure P. If V=242.0 inch cube when T= 220 degrees and P = 10 pounds square, what is the volume when T = 190 degrees and P = 20 pounds per inch square?

V=KT/P...WHERE K IS A CONSTANT
242=K*220/10......K=11

V=11*190/20=104.5
