Answer: It is a chemical change, it changes the actual composition of the object by removing water.
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
physical or chemical changes
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
Physical changes and Chemical changes are both the same - this would be a reversible change.
Yes, an object can undergo both physical and chemical changes. Physical changes involve changes in physical properties like shape, size, or state of matter without altering the composition. Chemical changes involve a transformation at the molecular level, resulting in the formation of new substances.
In a physical change the object changes appearance but in a chemical change the object turns into something different with different properties.
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
Changes in an object over time can be caused by factors such as wear and tear, exposure to environmental conditions, usage, or chemical reactions. These factors can lead to physical, chemical, or structural changes in the object.
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
There are no physical changes. there are only chemical changes.
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 physical change is when some thing's shape or volume is changed. But a chemical change is a reaction between two or more objects to create something new and you can't get back what you originally started with.
Physical changes are changes in something that affects the objects physical characteristics. Meaning things like the color, shape, amount. Example: cutting a piece of paper, painting a wall, etc. Chemical changes change what the object is made of. It can change everything, including the state the object(or liquid) is in.
physical or chemical changes
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.
