Hey allstar2.
Hint: You are given dV/dt and dP/dt, so use this and the product rule where T = (P*V)/10
Use the ideal gas law P=10T/V, where V is in cubic inches, T in Kelvins(K) to find the rate at which the temperature T of the gas is changing when the
volume V is 200in^3 and is increasing at the rate 4in^3/sec
pressure P is 5lb/in^2 and decreasing at the rate of 1lb/in^2/sec
