Does the derivative of a P(V) eqn give the eqn for change in Pressure?

AI Thread Summary
Taking the derivative of a P(V) equation can provide insights into the rate of change of pressure with respect to volume. The interpretation of this derivative depends on the variable with respect to which differentiation is performed. In general, derivatives represent rates of change, but their meaning varies based on the context of the differentiation. The discussion emphasizes that understanding the relationship between pressure and volume is crucial for interpreting the results correctly. Ultimately, the derivative can indicate how pressure changes as volume changes.

I know the integral of a P(V) eqn gives an eqn for work.

I was wondering if taking the derivative of a P(V) eqn gives an eqn for change in pressure?

What is your definition of an "equation for change in pressure?"

Gives rate of change.

For instance, if you take the derivative of velocity, you get acceleration, which is the rate of change of velocity.

No, the derivative of velocity with respect to time is acceleration. What you differentiate with respect to is important. For example, there are situations where velocity is given as a function of position. The derivative of such a velocity function is not acceleration.

Derivatives are rates of change with respect to the differentiation variable, but depending on what the differentiation variable is, the interpretation may vary.

So it would be rate of change with respect to volume?
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
