Is cracking an egg open a chemical or physical change?
see, cracking an egg open is cetrainly a physical change since the egg and the contents inside do not become a new substance they remain the same only thing is that the shape or the appearance or the physical structure changes that is why it is called as a physical change not chemical because its internal composition is the same to explain u better see , when u burn a paper, it turns into ashes n does not remain the same thing it earlier was, its composition changes, for this reason it is a chemical change. hope this info helps ,luck ,bye rutba
Is bursting of cracker a physical change?
Yes, bursting of a cracker is a physical change because the chemical composition of the cracker remains the same before and after the burst. The change is reversible and does not result in the formation of new substances.
Is the liquid propane in a barbecue evaporates away because the user left the valve open a chemical or physical change?
It's a physical change. Chemically, it's still propane - but it's physically changed from a liquid to a gas.
When soda goes flat is it a chemical or physical change?
When soda goes flat, it is primarily a physical change. The carbon dioxide gas that makes the soda fizzy escapes into the air, causing the bubbles to disappear. The composition of the soda remains the same, although its texture and taste may change.
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.
When you add baking soda to a salt and vinegar solution is it a chemical change or physical change?

Is a odor a physical or chemical change?
AnswerNeither. Odor is not a change at all. Odor is airborne molecules that have a particular smell. A change is a process and odor is not a process. The things which cause odors can be either physical or chemical. For instance, the body odor is caused by chemical changes, but if you open jar of a smelly chemical, that is a physical change (some of the molecules of the chemical are evaporating and are thus airborne).When talking about mixing chemicals and substances, a change in odor is a chemical change.(I assume this is what you meant when you asked is odor a chemical or physical change)

i think its chemical. Because the only thing physical that's related is opening the pop.
