A mixture is a physical change because it does not involve any change in the chemical composition of the substances involved. The particles in a mixture retain their individual properties and can be separated through physical means such as filtration or evaporation without any chemical reactions taking place.

Physical there still the same mixture but blended together not a totally different substance.
A physical change is needed to separate a mixture into its components. This can be achieved through processes like filtration, distillation, chromatography, or evaporation, which rely on the differences in physical properties between the components of the mixture.
A saltwater mixture is a physical change because it involves no chemical reactions. When salt dissolves in water, the salt molecules are simply dispersed throughout the water molecules without forming new substances. This change can be reversed by evaporating the water, leaving behind the salt crystals.
= a mixture is physical change... =
physical change
when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
yes it is a physical change. there is no chemical change
Forming a mixture
B.Forming a mixture
physical change You are making a mixture of the icing and food coloring, which is a physical change.
Heterogenous mixtures undergo physical change (I THINK)
Making an alloy is a physical change. An alloy is a mixture of metals.
Yes
Neither; it's a mixture of chemicals.
