rates of change Q (1 Viewer)

[akuchan]

P = k/V
P = pressure
k is constand and V is volume
if k = 100 for a certain gas, fine the rate of change in the pressure when V = 20

*lost* =/

is that the whole question?

 

[akuchan]

well..its
"According to Boyle's Law, the pressure of a gas is given by the formula P = k/V, where k is a constant and V is the volume of the gas. If k = 100 for a certain gas, find the rate of change in the pressure when V = 20"

find dP/dV when you plug-in k = 100 into the equation. (may be wrong)

I got -1/4 but I'm not sure what units that's in. Maybe kPA hour^-1?

ohh thx i got it, it is -1/4, forgot to change 100/V to 100V^-1
