Question

Help please!

Boyle's law for confined gases states that if the temperature is constant, pv=c where p is pressure,V is volume, and c is a constant. At a certain instant the volume is 75 cubic inches, the pressure is 3 psi, and the pressure is decreasing at the rate of 2 psi every minute. What is the rate of change of the volume at that instant?

Answer 1

I dont quite now how to solve this problem...I always get the wrong answer :/

Answer 2

Any Ideas how? If you could give me like step by step instructions on how you got your answer that would be awesome! :)

Answer 3

ok so this is as far as I've gotten with this

pc=c so 75*3=225 and if it decreasing at 2 psi a minute then after one minute c=75 and after 2 c= -75 so i would say its decreasing at a rate 150 psi's a minute

Answer 4

if I'm wrong i apologize i did my best!(:

Answer 5

I dont know if your wrong so yeah :P Thanks for helping :)

Answer 6

no problem!(:
