When matter undergoes a physical change, its physical properties change.
Physical properties include density, color, solubility, conductivity, hardness, kinetic and potential energy of molecules, volume, pressure, temperature etc. One or more of physical properties change when matter undergoes a physical change.
Remember chemical properties i.e. chemical composition and it's reaction with other substances remain the same.
Also it's mass remains the same.
When ice changes to water it's volume decreases, density increases, potential energy of molecules increases. Iodine is grey when solid but gives violet vapours on sublimation.
Changing the pressure or volume or temperature of a gas results in change of one or both of the other quantities. These are examples of physical change.
What else can I help you with?
If matter undergoes a physical change has its physical properties changed?
yes it does
What is changed when matter undergoes a phisical change?
When matter undergoes a physical change, its state may change (solid to liquid, liquid to gas, etc.), its shape or size may change, or its physical properties such as density or volume may be altered. However, the chemical composition of the substance remains the same before and after the physical change.
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 change in the conservation of matter?
The physical or chemical form of matter can be changed.
What can cause a matter to change?
through energy and inertia the matter changed.
