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.
Is cooking a physical or chemical change?
Cooking involve chemical reactions.
When a carrot is cooked is it a chemical or physical change?
When a carrot is cooked, it undergoes a chemical change because the heat breaks down the molecules within the carrot, altering its chemical composition. This results in changes in color, texture, and flavor, which are characteristics of a chemical change.
Which type of properties is easier to recognize physical or chemical?
Physical properties are generally easier to recognize compared to chemical properties because physical properties can be observed or measured without changing the substance's chemical composition. Examples of physical properties include color, size, shape, density, and melting point.
Good effects of physical and chemical change?
Physical changes include changes in state, size, shape, or appearance without altering the substance's chemical composition. Chemical changes involve formation of new substances with different chemical properties. Both types of changes can be used in industry for manufacturing products, such as refining metals through chemical reactions or changing the state of a substance to make it easier to transport.

Is burning a marshmallow a chemical change?
It is easier in this case to say why it isn't a physical change. As you cannot turn a roasted marshmallow back into an un-roasted one, A chemical reaction must have occurred. Cooking is normally a chemical change as you cannot un-cook something.
If you had a mixture of two substances and had your choice of using a physical change or a chemical change to separate them which would you prefer?
Physical change is preferable because it is easier than chemical method.

What are the advantages of physical changes?
Physical changes are advantageous because they do not alter the chemical composition of a substance, making it easier to reverse the change. Physical changes also usually do not require a lot of energy to occur, making them more efficient. Additionally, physical changes can often be observed directly through changes in appearance, texture, or state of matter.

How does physical weathering make the job easier for chemical weathering?
Physical weathering, such as cracks, creates more surface area for chemical weathering to occur on.
What is the physical change in food when it enters the esophagus?
the physical change in the change in food when the enters esophagus is when it has a chemical breakdown in your mouth with a mechanical breakdown the chemical breakdown is when your salivia is making the food moist the mechanical is when you chew the food so it easier for it to enter the esophagus and so the salivia can get it moist then your esophagus uses muscles to push the food down into your stomache

Why can't chemical changes be reversible?
Because its components have changed into something entirely different, so you can't pick out what has gone in. For example, if you mix water and salt, you can not take the salt out of the water because it has reacted with it to be changed into somthing different.
How is a chemical change useful to people?
To make people's lives easier and more comfortable
