  3. The Temperature Variable • The fire makes the particles go _____ and the ice makes the particles go ______. This represents the variable of _________ (also known as _____ energy), which is measured in units of _____. faster slower temperature kinetic Kelvin LAUNCH GAS SIMULATOR

  4. The Pressure Variable pump • The _____ adds more particles to the container, causing ____collisions with the walls of the container. This represents the variable of _______, whichis measured in units of ____. more pressure ATM LAUNCH GAS SIMULATOR

  5. The Volume Variable • The little man changes the amount of _____ the particles can occupy. This represents the variable of ______, which is normally measured in units of Liters space volume LAUNCH GAS SIMULATOR

  6. PRESSURE (atm) What three variables affect gases? VOLUME (L) TEMPERATURE (Kelvin)

  24. The Gas Laws • Gay-Lussac’s Law is an direct relationship (same direction) between Pressure and Temperature, while Volume is kept constant. • Charles’ Law is an direct relationship (same direction) between Volume and Temperature, while Pressure is kept constant. • Boyle’s Law is a inverse relationship (opposite direction) between Pressure and Volume, while Temperature is kept constant.
