hello everyone, recently i was studying thermodynamics and i think i got a basic doubt on what my book has to say and although i feel this is a small thing to ask but since i have no teacher with me, this is the best place i can think of.
so my book was saying about intensive and extensive variables in thermodynamics, it said to decide which variables are what half a equilibrium system and the values which do not change are intensive and the other are extensive.
so now they gave an example that if a system is halved, mass, volume, internal energy gets halved and pressure and temperature stay same, but now i have an question what if i half it in such a way that i take half moles of that gas in equilibrium and put in in different container of same volume, in such a case volume would remain same and pressure should get halved, so what are extensive and intensive variables in this case and how do we know?
thank you for reading and your replies.
