(4)__ properties can be observed without changing a substances chemical composition. color, hardness, and (5)__ are examples. other properties cannot be observed without changing the composition of a substance. these are called (6)____ properties. an example is the tendency of iron to form rust when exposed to air.

Explanation:

Matter is defined by mass and volume. A substance has a uniform composition. Physical and chemical properties describe substances. Physical properties can be observed without changing composition, like color, hardness, and density. Chemical properties require a change in composition, like iron rusting.

Answer:

(1) mass
(2) substance
(3) properties
(4) physical
(5) density
(6) chemical
