Understanding derivatives

If the instantaneous volume composition of the gas inside a tank is v, then what does dv represent?
Personal understanding: It’s the volume of gas in the tiny volume within the storage tank; why worry about this?
Elementary volume; it is recommended to refer to the definition of derivatives in advanced mathematics
It is the change in volume from V to V+Delta V, which is a volume element.
dv can be understood as a minor change in volume
Well, I realized later that it’s the change in the volume composition, that is, the change in the volume fraction, not the volume itself
As for this thing, don’t worry too much about it; it’s just a small size, you know
v is the volume composition, not volume. Please read the question carefully: P
It’s promising. The meaning of v is volume composition, that is, the volume fraction; it’s not the actual volume. So dv represents the change in volume composition
v refers to the volume composition, not the actual volume. It’s recommended to read the question carefully; as for P, I understood it later anyway, but thanks anyway
v represents the instantaneous volume composition; it’s not the actual volume. I was a bit confused when I saw a question on chemical engineering principles and didn’t understand the answer, but now I get it
