Hi there, this is a homework problem and I don't have a similar problem in my class notes.
Q - The pressure and volume of a gas are related by the equation PV^1.2 = 800. If the volume is increased at a rate of 15cm^3/s find the rate of change of the pressure, in Pascals per second, at the moment when the volume is 45 cm^3.
Anyway, most of my problems give me a shape to work with,ie; a rectangular tank, a cone, a sphere etc.
Can anybody shed light on how to begin this problem?
