#GASLAWS Created By: Madison Dodds RRT- ACCS  Objectives…. At the end of this lesson you will be able to… ~ Define the 3 main gas laws (Boyle’s law, Charles law, Gay-Lussac’s law). ~ Understand the variables and constants of each gas law. ~ Identify each gas law in a real world application. ~ Combine all 3 gas laws using the combined gas law.  Background Gas has different properties Many types of gas ( 0xygen, Nitrogen, Helium, Carbon Dioxide) We can observe gas pressure, temperature, mass, or number of particles, and volume. We can fix 2 of the 4 variables and study the other 2 by varying one and observing the other. www.grc.nasa.gov/www/k-12/airplane/aboyle.html  Boyle’s Law Robert Boyle was a British scientist who lived in the 1600’s whom identified Boyle’s law. Relationship between pressure and volume. Pressure and volume are VARIABLE, making temperature CONSTANT. The volume of gas in a closed container is inversely proportional to its pressure when temperature is unchanged. www.grc.nasa.gov/www/k-12/airplane/aboyle.html Examples…  Charles Law Named after Jacques Charles, a French scientist. Relationship between volume and temperature. When Pressure is kept a constant, the volume of a contained gas is directly proportional to it’s temperature. When temperature increases, volume increases. www.grc.nasa.gov Examples…  Gay –Lussac’s Law Named after Joseph Gay-Lussac, a French scientist. Relationship between pressure and temperature. When volume is kept constant, the pressure of a contained gas is directly proportional to its temperature. Examples… All 3 laws together make… COMBINED GAS LAW This is the relationship between the pressure, volume, and temperature of a fixed amount of gas. http://www.ck12.org/user:bwv2yw5zqgjjc3dhbi5uzxq./book/M rs.-Evans-Chemistry-FlexBook/section/16.2/ THANK YOU!!!!
