2. B OYLE ’ S L AW R EVIEW Pressure increases (goes up, is higher) Volume decreases (goes down, gets lower) When the temperature is kept the same (is held constant) © 2013 S. Coates http://www.grc.nasa.gov/WWW/K-12/airplane/Animation/frglab2.html

3. V= Volume i = inverse relationship (indirectly proportional) as one increases the other decreases P= Pressure

5. Pressure vs. Temperature What causes gas Pressure? Gas particles colliding with the walls of their container When the temperature increases- –H–Heat is added and the particles… move faster and collide with the walls of the container more often © 2013 S. Coates

7. Relating Pressure and Temperature When the volume of a gas is kept constant (the same) Pressure increases (gets higher) Temperature increases (gets higher) --- Look at Figure 18 in your Textbook on page 59 The number of gas particles in each container is the same… 1) Which Container is at Higher Pressure? 2) Why does this container have a higher gas pressure?
