1. The problem statement, all variables and given/known data the equation is PV = c; p = pressure, v = volume, c=constant. (also known as Boyle's law) the question: if volume is decreasing at a rate of 10cm^3/minute, how fast is the pressure increasing when the pressure is 100g/cm^2 and volume is 20 cm^3 2. Relevant equations none 3. The attempt at a solution dv/dt = -10cm^3/min dp/dt = ? equation: PV=c derivative: dp/dt x dv/dt = 0 dp/dt = -dv/dt but i know what im doing isnt right. can anyone help me? THANKS!
