finding W

[Peter Nguyen 2I]

Is the integral formula equivalent to -P(V2-V1)? can you use both to find -P delta V?

[Michelle Wang 4I]

Yes they are the same and I think you can use both interchangeably.

[Diviya Khullar 1G]

Yes -P(V₂-V₁ is what you get when you solve

[Eric Quach 1C]

Yep the formulas give the same answer. I think Dr.Lavelle was just using the integral to show how the P delta V formula was derived.

[Kavvya Gupta 1H]

the two equations mean the same thing just written in different ways

[George Ghaly 2L]

Yes, the integral just implies that a very small volume is being changed at every instant therefore it all can be summed up with an integral, while if the change of volume is large and sudden ten delta v can just be used.

[Christopher Anisi 2K]

The equations are the same, Dr. Lavelle wanted to utilize the integral to derive where P (delta V) came from showing that the sum of a small change in volume is equivalent to the integral.
