What happens when a substance changes state from a solid or liquid?
When a substance changes state from a solid to a liquid, it undergoes melting where it gains enough energy to break the bonds holding its particles together. When it changes from a liquid to a gas, it undergoes vaporization where it gains enough energy to overcome the forces of attraction between its particles.
An example of when matter undergoes a physical change?
Ice melting into water is an example of matter undergoing a physical change. The ice changes from a solid state to a liquid state without altering its chemical composition.
In what state of matter has mass and it and it is the same each time?
Mass is a property that remains constant in all states of matter: solid, liquid, gas, and plasma. The total mass of a substance does not change when it undergoes a phase change because mass is a measure of the amount of matter in an object.
What about matter can change and what does not change according to the law of conservation of matter?
mass cannot change quanity if it is not added or removed
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.
If matter undergoes a physical change has its physical properties changed?
yes it does
New substances are always formed when matter undergoes what?
chemical change.
When matter undergoes physical change does density change?
no
What happens to the composition of matter when matter undergoes a chemical change?
A chemical change involve a change of composition.
How do chemicals differ from physical changes?
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
When matter undergoes a chemical change does the composition of the matter change?
Yes, when matter undergoes a chemical change, the composition of the matter changes at the molecular level. New substances are formed with different chemical properties than the original substances.
When matter undergoes change of state what does it absorb or release?
Energy.
What is changed when matter undergoes a physical change give an example to explain your answer?
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.
When a substance changes to form a new substance with new properties it undergoes a what change.?
New substances are formed when matter undergoes a chemical reaction.
What can cause a matter to change?
through energy and inertia the matter changed.
What can change in the conservation of matter?
The physical or chemical form of matter can be changed.
What happens to matter when it undergoes a physical and chemical change?
A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes. An example of a chemical change would be burning paper and getting ashes. A physical change can be undone. An example of a physical change would be bending the paper because you can still get the paper back and no new substance is created.
