For the most part it is a chemical change because the soap bonds with the grease chemically. But also the action of rubbing your hands can cause some of the grease to come off, just like when you wipe your hands off on a paper towel.
nooope , it is a physical change so w.e for who Eva dnt noe what a physical change means losers hehehe
both. it changes the look of the object the greese was on and the soap reacted with the greese to get it off.
anything that bubbles is a chemical change
Yes, soap removing grease from hands is a chemical change.
the creation of soap is a chemical reaction.
Soap is a chemical product, not a change.
But washing involve some chemical reactions.
Yes
Physical.
Mostly the changes are not chemical at all, but physical changes. It does depend on what kind of stain and what kind of detergent. Soap itself only works by physical changes, and not by chemical means at all. However, things like bleach or other bleaching agents (such as whiteners) do cause chemical reactions to remove stains.Perhaps somebody can add some information here about how bleach and whitening agents work?See the Related Questions to the left for more information about how soap works.
you should just put grease on it every day and do not mess with it and it will heal regularly
Water cannot interact with grease,due to its high surface tension, so when the water is removed from the clothing after cleaning it, the grease remains. The fluids used to dry clean clothing are actually chemical solvents. They dissolve the grease, so when the solvent is removed, the grease is also removed.
Because as soon as water touches the hot surface, the bottom part, where the water touches, changes to vapour instantly! this happens so fast, that when it expands, it expands with explosive force and even pushes the water on top of the vapour outwards. this may carry some oil with it.
Like dissolves like. Lipstick is made of greasy or polar molecules, and so is petroleum jelly. Water is a polar molecule. Just like oil and water don't mix, nor does water and lipstick. Water is good at removing polar molecules (like salt for instance), but not good at removing grease. That is why you have to use soap to clean clothes -- because water alone does not remove grease or oils.See the Related Questions for more about how soap works.
It is a chemical change.
Frying bacon is a chemical change. In addition to simply heating the bacon, frying it causes certain molecules to react and change. For instance, some protein molecules may be broken down. This is why cold fried bacon tastes different than cold raw bacon.
A hazardous chemical in the home is ammonia. Ammonia is also commonly known as bleach and it is effective and killing germs and removing grease from surfaces.
By mixing wet and dry ingredients there will be a chemical reaction.For instance preparing pancakes, when mixing flour,sugar,salt and baking soda with grease,eggs, vinegar and milk these combined will form a solid pancake.
No. You're not changing the chemical makeup of anything involved -- soap, tablecloth, or grease. The soap emulsifies the grease so that it can be dissolved in the water contained in the cloth you use to wipe it up.
