What is an infinitesimal change and how do you identify it?

An infinitesimal change is a change over a very very very short period of time, so short, that you can almost consider t as being 0. You'll see this in a reversible process.

Its the same as taking the derivative in calculus. We used it in thermodynamics to see what the effect of changing pressure or temperature would have on the system

Infinitesimal doesn't necessarily have to do with time, it's just denoting a mathematical value smaller than anything measurable. A change that's infinitesimal can refer to time, pressure, volume, temperature, or anything you want to assign it to since it's unitless.
