In a chemistry assignment we used the ideal gas law (PV = nRT) as follows to find the volume of a glass container which doesn't change throughout the course of removing some gas from it: V = (∆n)RT/(∆p). How is this allowed algebraically? Is it always true that if A*B = C*D*E, then (∆A)*B = (∆C)*D*E?

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
