The 3 States of Matter include gases, liquids and solids.

###### Analyzing the States of Matter

Concept #1: Under varying conditions of pressure and temperature, most substances can exist in 3 states of matter.

Concept #2: States of Matter

Example #1: An unknown substance has a volume of 12.1 L and upon quadrupling the pressure has an unchanged volume. Which is the likely physical state of the unknown?

Practice: Which of the following choices will have the lowest observed viscosity?

Practice: Nitric acid, which is used in the production of fertilizers, plastics and dyes, has a melting point of – 42ºC and a boiling point of 83ºC. Determine its physical state at a temperature of 110ºC.
