RELATED RATES
The adiabatic law (no gain or loss of heat) for the expansion of air is ??^1.4=?, where P is the number of pounds per square unit of pressure, V is the number of cubic units of volume, and C is a constant, at a specific instant, the pressure is 60 lb/in2 and is increasing at the rate of 10 lb/in2 each second. If ?=516 . What is the rate of change of volume at this instant?
(I'm thankful if you already answered the problem, but please don't do it twice. I'm trying to find different ways and perspective of solving it.)
