Chemistry Review

Density is a measure of the amount of mass in a given volume. What tool could we use to determine the density of an object?

• scale

• calculator

• ruler

• graduated cylinder

What make physical properties different from chemical properties?

• physical properties relate to elements and compounds

• physical properties appear only after a chemical change occurs

• physical properties can be observed without changing the identity of the substance

• physical properties describe elements in the solid state

gas particles changing states to solid particles is a physical change rather than a chemical change because

• the particles get smaller

• the volume of the matter decreases

• the composition of the matter stays the same

• the particles change into particles of a different substance
