What is a physical change of matter?
A physical change in matter occurs when the shape or form of matter changes, but there is no chemical reaction. If someone were to melt a sugar cube, that would be an example of a physical change.
Does a physical change occurs when matter changes state?
no physical change does not change matter
What properties of matter are affected by a physical change?
The properties of matter that are affected by a physical change is for example, there is a house then it gets destroyed that is a physical change.
Can matter be created or destroyed?
Matter can not be created or destroyed in a chemical or physical change. Which is known as the Law of Conservation of Mass. Matter can only be converted, this conversion happens during a chemical change.
When a physical change occurs in a sample of matter which is the matter that does not change?
composition
What happens when a physical reaction occurs?
For example, the change in the state of matter.
What is a physical change of matter?
A physical change in matter occurs when the shape or form of matter changes, but there is no chemical reaction. If someone were to melt a sugar cube, that would be an example of a physical change.
Is breaking glass a chemical reaction?
No, this is a physical reaction because no matter has exchanged etc. Instead, the lattice structure of the glass has been broken- which is simply physical. (Not even that sophisticated a physical change, as glass has no lattice structure.)
What does not change when a substance changes matter?
During a physical change, the matter of what the substance is made out of doesn't change.
Is evaporation a chemical or physical reaction?
Evaporation represents the uptake of energy by the liquid that results in a physical change. (phase or state of matter)
What change in matter can be reversed?
A physical change in matter occurs when the shape or form of matter changes, but there is no chemical reaction. If someone were to melt a sugar cube, that would be an example of a physical change.
Why is salt in water a physical change?
Dissolving salt into water is a physical change because no chemical reaction takes place, while the state of matter of the salt changes.
What happens to the composition of matter during a physical change?
It can change from a gas to a solid to a liquid, or from a liquid to a solid to a gas. This change does not affect the composition of the matter.
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
Which is A change in size shape or state of matter?
a change in size, shape or the state of matter is a physical change. True for A+.
Can matter change states after a physical change?
Yes, matter can change states after a physical change.
A physical change occurs when matter changes state?
no physical change does not change matter
