No. An example of a physical change is cutting up a carrot. Physical changes occur when the shape of the substance or the state (gas, liquid, solid) of it change. In the example, the carrot's shape is changed (1 piece to many pieces), so it's a physical change. The composition never changes.
During a physical change, the chemical makeup of matter remains the same. The atoms and molecules that make up the substance do not change their identities, only their arrangement or state. This means that no new substances are formed during a physical change.
Yes, that is correct. A physical change is a change in a substance that does not involve changing its chemical composition. This can include changes in size, shape, or state of matter without altering the substance's fundamental makeup.
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.
When matter undergoes a physical change, its state or appearance may change, but its chemical composition remains the same. For example, when water is heated and turns into steam, its physical state changes from liquid to gas, but it is still composed of H2O molecules.
In a physical change, the chemical composition of the substance remains the same, meaning the elements or molecules present do not change. Additionally, the mass of the substance is also unaffected, as no matter is either created or destroyed during a physical change.
yes
False. In a physical change, the makeup of matter remains the same, only the physical properties like shape, size, or state are altered. No new substances are formed during a physical change.

The physical or chemical form of matter can be changed.

During a physical change, the chemical makeup of matter remains the same. The atoms and molecules that make up the substance do not change their identities, only their arrangement or state. This means that no new substances are formed during a physical change.
If by matter you mean molecules / atoms then no. Physical change is when the look / shape of something is changed but not its chemical structure, chemical change is when the molecules that make up the object n question are changed.
Yes, that is correct. A physical change is a change in a substance that does not involve changing its chemical composition. This can include changes in size, shape, or state of matter without altering the substance's fundamental makeup.
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
It's not a physical change. Rather, it is a sign of an already completed chemical reaction.
