My question has already been answered in parts at Difference between state of matter and phase
But for deep and real understanding I have to ask for the difference between phase and a heterogenous mixture :
Say we have a bowl made of glass. The bowl is filled with a few different solid rocks on the ground, water in the middle and some oil on top.
I try to analyse this situation for understanding:
- There is a phase of oil on the top
- There is a phase of water in the middle
- There is a phase of rocks on the ground
- Since the rocks on the ground are not equally the same they are a bunch of single phases that do not mix up to each other
- The rocks on the ground are also a heterogenous mixture
- The air above the water is a phase of gas
- The glass is a solid phase of silicon
Is that correct?
