I am having trouble with physical applications of calculus. Can someone help me with this question?
When a gas expands without a change in temperature, the pressure 'p' and volume 'v' are given by the relation pv^1.4=k, where k is a constant. At a certain instant, the pressure is 25gm/cm^2 and the volume is 32cm^3. If the volume is increasing at a rate of 5cm^3/s, at what rate is the pressure changing at this instant?
