  1. Agenda Attendance Hand in your Labs Pass the problem on Hot air balloon project

  2. Pass It On • How many moles of CO2(g) is in a 5.6 L sample of CO2 measured at STP? • a) Calculate the volume of 4.50 mol of SO2(g) measured at STP. b) What volume would this occupy at 25°C and 150 kPa? (solve this 2 ways)

  3. (1 atm)(5.6 L) ( 0.08206L·atm·mol-1·K-1 )(273 K) (101.3 kPa) • Moles of CO2 is in a 5.6 L at STP? P= 1atm, V= 5.6 L, T= 273 K PV = nRT (1 atm)(5.6 L) = n ( 0.08206 L·atm·mol-1·K-1)(273 K) • a) Volume of 4.50 mol of SO2 at STP. P= 101.3 kPa, n= 4.50 mol, T= 273 K PV=nRT = n = 0.25 mol (101.3kPa)(V)=(4.5mol)(8.31kPa•L/K•mol)(273K) (4.50 mol)(8.31 kPa•L/K•mol)(273 K) V = = 100.8 L

  4. P1V1 P2V2 = T1 T2 (101.3 kPa)(100 L) (150 kPa)(V2) = (273 K) (298 K) (150 kPa) (101.3 kPa)(100.8 L)(298 K) = 74.3 L (V2) = (273 K)(150 kPa) • b) Volume at 25°C and 150 kPa (two ways)? • Given: P = 150 kPa, n = 4.50 mol, T = 298 K (4.50 mol)(8.31 kPa•L/K•mol)(298 K) V = = 74.3 L From a): P = 101.3 kPa, V = 100.8 L, T = 273 K Now P = 150 kPa, V = ?, T = 298 K

  5. Hot Air Balloon Project

  6. Project: ResearchAssignment- 35% Hot Air Balloon- 60% Peer Evaluation- 5%

  7. In ordertobuildyourhot air balloon, youwillneedtoapplyyourknowledgeonthefollowingtopics: Propertiesof Gases Boyle`sLaw Charles Law Gay-lussacLaw Lawof Ideal Gases (Uses)

  8. Individual Research Assignment (35%) You can do : Poster, paper, PowerPoint, video, etc. Due date: Tues/Wed May 8th/9th You will have to do some research and turn in a individual project on: • One of the Gas Law Scientists • Hot Air Balloons- History And Uses. • Why you care about Gas Laws in scuba diving • Dirigible Hindenburg Accident • If you come up with anything else just ask You can email it to me: Joscelyn.martin@hotmail.com Use your own words Make sure to tell me/ask me about what your planning to do. Make sure to include your name, date and period number.

  9. HOT AIR BALLOON (60%)- Groups of 3 or 4 • MATERIALS: • TEMPLATES • COLORED TISSUE PAPER • SCISSORS • RULER • GLUE • MAKE SURE ALL THE MEMBERS OF YOUR TEAM WORK ORDERLYand QUIETLY. • ALWAYS CLEAN YOUR WORK AREA.
