What does physical and chemical change have in common?
A physical change to an object is a change in properties not involving the chemical makeup. In other words, a physical change is any change you can make to an object without changing the actual substance. (I.e. state of matter, size, shape, color . . .etc.) A chemical change is a change that forms a new substance through a chemical reaction. A chemical reaction is often signaled by bubbling or fizzing, but the only real way to prove a chemical reaction is by coming up with a new substance. So physical changes leave you with the same substance (slightly altered in appearance/texture etc.), but chemical reactions give you a new substance.
What kind of change occurs when salt dissolves in water chemical or physical?
When salt dissolves in water, it undergoes a physical change, not a chemical change. This is because the chemical composition of salt (NaCl) remains the same before and after dissolving in water. The salt molecules are simply dispersed in the water, forming a homogeneous mixture.
What the difference between a physical change and a chemical change?
A physical change, for instance, is melting a solid chunk of ice in a pot. The ice is a solid, melts to a liquid when you supply energy (heat) to it, and when even more energy is supplied - will change to a gas (water vapor or steam). The components of water, H2O, do not change in any of these processes. They simply have very little(ice), or alot of energy(steam). A chemical change, would change the chemical properties of that H2O molecule. For instance, when you place water in between a high voltage capacitor (two conductive plates spaced apart), this energy will strip the hydrogen from the H2O molecule and leave you with O2, and gaseous Hydrogen. This is a chemical change.
Is mixing sugar in water a physical change or a chemical change?
ANSWER:A physical change. Nothing new is made from the solution and they both can be separated later by using heat to evaporate the water, leaving the sugar behind.
Is bubbling and fizzing a physical change or chemical change?
Gas bubbles are a chemical change. A common example can be soda. The bubbles in the soda are carbon, thus soda is carbonated, when you leave soda open and out in the open the carbon reacts with the oxygen in the air and forms carbon dioxide. Since there is a new chemical composition of the soda since it has lost carbon, also know as going flat, this is a chemical change. The above example is incorrect. The bubbles coming out of soda is not carbon reacting with oxygen;the bubbles are already carbon dioxide. Does pencil lead react with oxygen? The carbon dioxide in your soda is dissolved in solution. Gas bubbles in most other situations though ARE a sign of a chemical change.
If you leave an orange out for days and there is nothing but the juice is dry will that be a chemical physical change?
Chemical change.
Is a leave changing color a physical change or chemical?
I think it is a physical change because if it's a chemical change it would be a whole new substance but it's only a change of color. Re: No it can't be a physical change because it's irreversible. There is a chemical reaction occurring in the leaves, so it should be a chemical change.
If you leave milk in the refrigerator for too long it begins to go sour. Is this an example of physical or chemical change?
This is a chemical change.
Dissolving table salt in water a chemical or physical change?
i think its a phyiscal change cause wen u leave it outside to evaporate u can still get the salt out
Is dissolving salt in water a physical or chemical change and why how could you verify your answer?
Dissolving salt in water is a physical change because it does not alter the chemical composition of either the salt or water molecules. This change can be verified by allowing the water to evaporate, which would leave behind the original salt crystals without any chemical changes occurring.
What type of change is it when you leave a bolt outside and it becomes rusty chemical physical phase or environmental?
this is a lame website !!
Is evaporating sea water to leave salt physical or chemical?
chemical
A physical change differs from a chemical change in that waste products are formed through chemical changes?
In a physical change, the substance retains its chemical composition, but its physical state may change, such as melting or freezing. In a chemical change, the substance undergoes a change in its chemical composition, resulting in the formation of new substances.

If you leave your bicycle in the rain what does it become?
If you leave your bicycle in the rain it becomes a wet bicycle, or possibly a wet, rusty bicycle. I hope that was the answer you were looking for.
