What change might be observed when a substance is heated?
When a substance is heated, it may undergo physical or chemical changes such as melting, evaporation, sublimation, or decomposition. These changes can result in alterations in the substance's physical state, color, texture, or chemical composition.
What is one major difference in a physical change and a chemical change is?
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.
Is hammering metal into a flat sheet physical or chemical change?
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
How is physical change and chemical change different?
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.
What are physical and chemical changes and how are they the same and how are they different?
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.

Would freezing an object be physical change or chemical change?
Physical changes and Chemical changes are both the same - this would be a reversible change.
What object has physical and chemical changes?
My chocolate bunghole, g doub out
Different between physical and chemical change?
In a physical change the object changes appearance but in a chemical change the object turns into something different with different properties.
Is freeze drying physical change or chemical?
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
What caused changes in the object over time?
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.
Does a phsical change or chemical change affect the matter in an 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.

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.
