2. Most matter expands when heated and
contracts when cooled
General increase in the volume of a
material is its temperature is increased
Fractional change in length or volume per
unit temperature change

4. Charles Law (constant pressure)
-For a given temperature change, all
gases expanded by the same amount
of volume.

5. Boyle’s Law
-If temperature held constant, the
volume of the gas varies inversely
with its pressure.
- 𝑃1 𝑉1 = 𝑃2 𝑉2
