This demonstrates a physical change. The way the clay looks is now physically different because the shape of it has changed.
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
physical, because it can be easily reversed
Yes, molding clay into a new shape is a physical change. This process involves altering the form of the clay without changing its chemical composition. Once the clay is reshaped, it retains its original properties, making it a reversible physical change.
Physical.
no a change in shape is physical change
No. it is not. It is a physical change.
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
It is a physical change because only its shape changed, not its chemical composition.
It is a physical change unless it is caught on fire to mold into a different shape then it would be a chemical change. The substance that does change shape does not develop new chemical properties.
Purely physical.
False. Changing the size and shape of pieces of wood is a physical change, not a chemical change. A chemical change involves the alteration of the chemical composition of a substance, while a physical change only affects the physical properties of a substance.
