Washing clothes is a physical change, not a chemical change. The dirt and stains on the clothes are being physically removed, but the molecular structure of the clothes remains the same.
It is a Physical Change because i dont know but im sure that is a physical change :P
The chemical formula for washing soda is Na2CO3.
Washing hair is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, while a physical change only alters the physical properties, such as shape, size, or state, without changing the chemical makeup. When you wash your hair, you are simply removing dirt, oil, and other substances from the hair shaft without altering its chemical structure.
washing clothes is a chemical change because the dirt and stains dissolve in the solution that the clothes are being washed in
I think it is a physical change Improvement: It's actually a series of chemical changes. As different chemicals are added they break and make bonds within the protein make-up of the hair.
to wash your cloths
Washing shoes is a physical change because the composition and chemical structure of the shoes remain the same before and after washing. The change is reversible and does not alter the material at a molecular level.
They washed their cloths by hand until the wringer washing machine was invented

Physical. The water changes its state of matter from liquid to gaseous. No chemical reaction (i.e. change) going on there.
it is chemical because it can not be reversed

You do that when you wash you cloths by walking through a car wash fully dressed.
Ignition of a match is a chemical process.
in 1950 my mom used an electric washing machine.
== == Washing Soda+lemon juice=co2+other products == == A chemical reaction has taken place between the reactants, washing soda and lemon juice. Carbon dioxide is one of the products. the chemical change cannot be reversed. So it is a irreversible change.
