A PHYSICAL CHANGE MEANS CHANGE IN EXTERNAL APPEARANCE .
A CHEMICAL CHANGE MEANS THE CHANGE IN THE PARTICLES BY WHICH IT IS MADE up OF.
Physical Changes are d changes which are reversible .In this change we can get the products back. eg-Mixing of water and salt ,we can get salt back .
Chemical changes are d changes which are irreversible . In this change we cannot get the products back . eg- Burning of candle , we cannot get the matchstick back after burning .
Chemical Change: A chemical change is a reaction that transforms (changes) a substance into a new substance or substances with different properties.
Physical Change: No new substances are made. It is fairly easy to reverse this kind of change. An example would be dissolving salt in water. The change can be reversed simply by evaporating the water.
A phsical change is when something changes from a solid to liquid, liquid to ect. ect. The substance is still the same.
A chemical change is when the structure of the atoms in something change eg a metal forming a metal oxide or cooking an egg.
Physical changes do not change the makeup nor the properties of a substance, Cut a large piece of paper, and it is still paper.
Chemical changes like burning paper --- you can't write on it anymore. Properties have changed because the makeup has changed.
physical: what changes on the outside
chemical:what changes on the outside
a physical change is reversible but a chemical change is not ora physical change is a change in which no new substance is formed; a chemical change is were one or more substances are formed
A physical change doesn't involve chemical rections and modification of the chemical struture - chemical changes involve chemical reactions.
Chemical change
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
Physical change
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
physical change
Something that tarnishes goes through a chemical change versus a physical change.
by drawing 2 circles and compare and contrast chemical and physical change
If a new substance is produced.
Chemical broooooooooooooooo niga
it is a chemical change
Chemical I think
physical as the chemical structure does not change.
A physical change
Physical - there are no chemicals involved
Chemical change
Itβs a physical change π
