Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
Is sublimation of naphthalene a physical or chemical change?
A liquid evaporating is a physical change. Anything changing from a solid to a liquid (or liquid to solid), or from a liquid to gas (or gas to liquid) is a physical change).-Alec Vasquez
Is the melting of ice a physical change or a chemical change?
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
Is a solid changing from a liquid to a gas a physical or chemical change?
The change of a liquid to a gas is a physical change because its chemical properties do not change. Molecules of the liquid are just moving farther apart, therefore turning into a gaseous state.
What are two kinds of changes that occur in matter?
The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
Is candle wax hardening a physical or chemical change?
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
What is an example of a physical change in baking?
both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change
Is pouring liquid a chemical change or physical?
A physical change.

Is liquid to gas chemical change?
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
Is changing liquid to gas a chemical change or physical change?
physical change
Is liquid to a gas chemical or physical change?
it is a change of state, a physical change.
Is dissolution of a solid in a liquid physical or chemical change?
a physical change
When a liquid is expanded by heat is that a chemical of physical change?
It is a physical change because the chemical composition of the substance does not change.
Is molten lava hardening into a rock a physical change?
It's a physical change - more intermolecular bonds (bonds between different molecules) are formed due to the cooling of the matter, and the state of matter changes from liquid to solid. The chemical makeup of the lava does not change.
Is wax solidifying a physical or chemical change?
Yes becasue when the atoms inside the wax start to change, they all form and become a solid. this is what is now called replacement.
Is a liquid at normal temperatures and pressures a physical or chemical change?
A liquid at normal temperatures and pressures is a physical change. When a substance changes from a solid to a liquid or from a gas to a liquid without any chemical reactions taking place, it is considered a physical change.
