Mixture





I got all this thinking from this link.Physical change is when the substance not change identity. Its like that clay and clay is always clay.  Or thhat if you change something it will still be the first thing. A Mixture is when you put something that is like food. Or something diffrent. A mixture has to be or than one thing that ramian thier physical qualities. . To mix something. You have to put stuff together. Yoou could take them out seprtly physically. Parts of mixture can't be physical change. Mixtures can be changed by phyisical means. a solid and a liquid ar mix together you could seprete it by a filter. Salt and water can be seprated by the water evaporating. When you use physical change to do something You don't change the part identity.
