How do decantation and filtration differ? Which should be faster?

Why should you never place a hot object on the pan of balance ?

Expert Solution

Filtration differs from decantation in such a way that the liquid phase which passes through a semipermeable substance like a filter, but in the case of decantation, the liquid phases are separated from the solid phase by carefully pouring off the liquid. Decantation does not involve the use of another substance to get the separation, and is faster than filtration.

Hot objects will create a convection current in the air around the balance pan. This oscillating force diminishes the air pressure on the balance pan and can make it tough to obtain a constant reading. and also, it creates a buoyancy effect by emiting energy in the form of heat and will display a reduced mass.
