Is a given change a chemical or a physical change?
It depends. Physical can be easily reversed. Chemical is hard, if not impossible to reverse.
How do you reverse the process of making a mixture a physical change?
= a mixture is physical change... =
Is condension a chemical or physical change?
actually it is a CHEMICAL change...because physical means you cant reverse the compounds like plaster of Paris mixed with vinegar turns hard but is an experiment that you cannot reverse back!! xxx
Is melting butter a physical change or chemical change?
As you may know, determining whether a change is chemical or physical can sometimes be a real pain! This particular change is a hard one. If your talking about butter slightly melting on a hot day because it was left out on the counter, THAT is a physical change and is reversible by simply putting the butter into the fridge. However, melting butter on the stove and having it completely turn to liquid and turn a little brown, THAT is a chemical change and is hard to reverse... a chemical change has occurred while the butter was over the heat.
Is sugar dissolved in water a chemical or a physical change?
it s a physical change.
Which is easier to reverse chemical or a physical change?
Physical changes are generally easier to reverse than chemical changes. Physical changes involve a change in state or appearance without altering the chemical composition of a substance, so reversing the change often involves a simple process like melting, freezing, or evaporating. In contrast, chemical changes involve the formation of entirely new substances with different chemical properties, making them more challenging to reverse.
What is the most important difference between a chemical and a physical change?
The chemical change produces one or more new substances, the physical change does not. Many people will tell you that the difference is that chemical changes can't be reversed, but this is an oversimplification used to help students when they are first learning about the types of change. In fact it's possible to reverse chemical changes, though it's sometimes quite difficult. Then again, some physical changes are hard to reverse too.
Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
Is a chemical change easier to reverse then a physical change?
No, chemical changes are typically more difficult to reverse than physical changes. Chemical reactions involve the creation of new substances with different chemical properties, making it challenging to reverse the reaction and return to the original substances. Physical changes, such as changes in state or shape, usually involve rearranging the same particles and are more easily reversible.
Can appliances have a physical change?
A physical change is something simple, or easy to reverse, like a change of state (Such as ice melting into water). It always occurs after some time on metallic bodies.
Because change the identity of the substances involved they are hard to reverse?
Chemical changes are hard to reverse because they involve the formation of new substances with different chemical properties than the original substances. This typically requires energy input or a specific reaction pathway to revert back to the original substances, making the process difficult to reverse.
Is butter turning hard when cooled a physical change?
Yes, whenever a substance changes its physical form without changing the chemical composition, it is considered a physical change. In this case, liquid butter turning hard does not become a different substance, so it is a physical change.
