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
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 dew forming on a leaf a physical or chemical change?
It is a physical change because is it changing the leaf? No, no it isn't so it is a physical change.
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 liquid tree resin hardening into amber physical or chemical change?
Physical... chemically, it's still the same substance,
Is changing liquid to gas a chemical change or physical change?
physical change
Is changing of a solid to liquid chemical or physical change?
No it is a chemical
Is a chemical change a liquid becoming a gas?
No, a liquid changing to a gas is a change of state or a physical change.
Is liquid becoming a gas a chemical change?
No, a liquid changing to a gas is a change of state or a physical change.
Is boiling does that changes as a physical or chemical?
Boiling is a physical change because the substance is changing from a liquid to a gas without changing its chemical composition.

Silver melts at 961 Celsius Is it chemical change or physical change?
This is a physical change because you are changing it from a solid to liquid
Is liquid becoming a gas a chemical chang?
No, a liquid changing to a gas is a change of state or a physical change.
Is a block of ice changing from a solid to a liquid a physical change?
Yes, the process of a block of ice changing from a solid to a liquid is a physical change because the chemical composition of water remains the same during this transition. The change in state from solid to liquid is reversible.
Is water changing from liquid to gas a chemical reaction?
No, water undergoing a phase change is a physical change, not a chemical change.
Can heating water to change it to water vapor be a chemical change?
No, this is definitely a physical change, absolutely not a chemical.
Is changing from a gas to a liquid a chemical change?
No, changes of state such as this are physical changes.
