Happy PLC Day! Pick up Phet Activity and sample problems Add the following terms to your learning goals sheet: Ideal Gas – particles have no volume and have no attraction towards each other Real Gas – particles have volume and have some attractive forces towards each other Ideal Gas Constant R: R = 8.31 L*kPa / mol*K

Answers to Practice Problems 1. V = 124 L 2. V = 4.46 L 3. P = 2.58 kPa 4. V = 8.36 L 5. P = 68.3 kPa 6. P = 415 kPa

Ideal Gases Do not exist Real gases behave most like an ideal gas at: High temperatures Low pressures

Homework: Gas Law Practice Problems #7-13 Moodle Lab quiz – open until Mon at 11pm Knowledge Check for 12.1, 12.2 and 12.3 (gas law calculations) open from Wed at 5pm – Thurs at 10pm
