(adsbygoogle = window.adsbygoogle || []).push({}); 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!
