When water freezes to form snow is it a physical or chemical change?
physical change, because the frozen rain can be turned back into rain (or water if you want to be exact) But a good example of a chemical reaction would be, you have the ingredients for a cake, you take those ingredients, mix and bake them, that would be a chemical reaction because it cannot be turned back into a cake
Are fireworks an example of physical or chemical change?
Chemical change. A good hint for this one is that there is fire involved, which usually means that the chemical itself is being changed. The constituent materials oxidize (burning quickly - explosion - is very rapid oxidization) and form new compounds i.e. the chemicals change.
A chemical change is a change in the of a substance?
A chemical change is a change in which a change of matter that produces one or more new substances is a chemical change.Unlike a physical change, a chemical change produces new substances with new and different properties. Examples of chemical changes are combustion,electrolysis, oxidation,and tarnishing, frying an egg, burning of wood, cutting a tree.
Is light a physical or chemical property?
Radiation would be a chemical property. Remember, a physical property is something that does not change the composition or "identity" of a substance whereas a chemical property is something that does. Since anything exposed to radiation for a good amount of time would experience change in composition, it is thus referred to as a chemical property.
Is old ham in the refrigerator a chemical change or physical change?
Old ham in the refrigerator undergoes chemical changes due to the breakdown of proteins and fats by bacteria and enzymes. The formation of new compounds during this process is characteristic of a chemical change.

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.

When a precipitate is formed from the mixture of two chemicals is it a physical or chemical change?
Chemical. Four good indicators of a chemical change are: # Change in Color # Change in Temperature # Creation of a gas # Creation of a precipitate These don't always indicate a chemical change, but are good guidelines if you are unsure.
Is drying leaves a chemical change or a physical change?
Drying of leaves is a physical change because neither it changes its composition nor does it have any different properties from the original one.
The difference between a physical and a chemical change?
A physical change the chemical compounds remain the same in the change, in a chemical change the chemical compound changes. A good example is if you move a raw egg around in a pan, some of the egg may separate but it's still a raw egg. If you turn on the heat and cook the egg you are chemically changing the egg and it so no longer a raw egg.
