Measuring physical properties changes the chemical identity of the substance.

It makes to substance develop a deep seeded distrust of humans.

Observing physical properties has no effect on the substance.

The substance will undergo an exothermic reaction.

There is no difference between a physical and chemical properties?

Observing a chemical property results in the creation of a new substance while observing a physical change does not change the substance.

Physical properties are usually room temperature but chemical properties are very hot.

Mass is created in a chemical reaction.

New chemicals formed from a chemical reaction have a larger overall mass than the original reactants.

Mass is created in a physical change.

Mass is never created or destroyed.

the temperature at which a substance changes from a liquid to a solid or a solid to a liquid by the loss or addition of heat; for water this temperature is 0°C.

the decimal measuring system based on the meter, liter, and gram as units of length, volume (capacity), and weight or mass.

a combination of two or more substances that can be easily separated in some physical way.

properties of matter that can be observed, measured, or changed without changing the matter itself.
