Matter and Energy Test Flashcards
Chemical Property or Physical Property?
Salt melts at 801C
Physical Property:
The boiling point and melting point are physical properties
Chemical Property or Physical Property?
Fumes from ammonia and hydrochloride acid mix to produce a white smoke.
Chemical Property:
the ability of a substance to react to form new substances; such as flammability and susceptibility to corrosion
Define Extensive Property

Define Physical Property
A characteristic of a substance that can be observed or measured without changing the identity of the substance.
Define Physical Change
A change in properties such as texture, shape, or state.
Suppose there are two glasses in front of you, one containing water and one containing gasoline.
What physical properties could you use to differentiate between them?
Physical Properties: Odor, Color, Viscosity
What is the difference between a chemical and physical property?
Physical properties can be observed and measured without changing the substance at which you are looking.
Chemical properties can only be observed when you change the chemical structure of the substance.
