yes,sometimes both changes occur together. For example, when a person eats chocolate and then digests it a physical and a chemical change takes place. When the person chews the chocolate and breaks it into smaller pieces - it is a physical change. No new substances have been formed yet.Once acted upon by saliva and other digestive juices, the chocolate is broken down into other simpler substances, which can be absorbed by the blood. This is a chemical change.
yes
eating of chocolate : biting cuts the chocolate - physical change( it still remains chocolate)
digesting it is chemical change
yes absolutely, you could always split(physical) a burning(chemical) log with an axe.
or crinkle up some aluminum foil in a bowl of acid at the same time.
Yes, it is possible.
[object Object]
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
Length is a property not a change.
Physical there still the same mixture but blended together not a totally different substance.
Getting covered with soot would be classified as a physical change rather than a chemical change.
Hammering gold into foil is a physical change because the gold does not undergo a change in its chemical composition during the process. The structure and properties of gold are altered physically by being flattened into foil, but its chemical identity remains the same.
In a physical change the object changes appearance but in a chemical change the object turns into something different with different properties.
Easy, chemical change.
i am pretty sure it is a physical property! :)
Sublimation of mothballs is a physical change. Sublimation is the process of a substance transitioning from a solid directly to a gas without going through a liquid phase. It does not involve a change in the chemical makeup of the substance.
An orange is a physical object and is not any kind of "change"!

Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
Because a physical change just alters the appearance of an object, where as a chemical change alters the texture or state of an object.
Physical changes and Chemical changes are both the same - this would be a reversible change.
Length is a property not a change.
