Presentation Transcript

  1. Fall wk 3 – Thus.14.Oct.04 • Welcome, roll, questions • Josh Skov • break • Calculus Ch.1 and Physics Ch.18 • Looking ahead Energy Systems, EJZ

  2. Welcome Josh Skov • Sustainability guru • Greener by association • The Good Company (details on our research webpage • How to measure sustainability indicators on campus?

  3. Finish Physics Ch.18 • Key points? • Insights from team discussion? • Questions? • Review of heating • Gas cycles and work

  4. Energy and heat - review 1. Which are not units of Energy? • Joules B. ergs C. Kilowatt-hr D. Watts 2. Which is a bigger temperature change? A. DT = 1°F B. DT = 1°F • How does the temperature of water change as it freezes? A. Gets colder B. unchanged C. Gets warmer

  5. Energy and heat - review Match each heat transfer mechanism to its medium: • Conduction 1. Photons B. Convection 2. Solids in contact C. Radiation 3. Flowing fluid

  6. Heat, energy, work - review Heat required to raise the temperature of a substance: Q = m c DT Heat required to change state: Q = m L Work done by (or on a gas) = area under P(V) curve Practice: Problem # 27, 29, 32, 33

  7. Heat, energy, work - new Gas cycle: Heat in = Work done + internal energy Q = W + E Electric Power = Voltage * Current: P = VI (p.695) Ohm’s law: Voltage = Current * Resistance: V = IR Radiation: Prad = s e A T4 Practice Problems: Ch.18 # 94, 52, Ch.26 # 43(a)

  8. Phys 18 HW Thermal (and basic) physics problems due this Thus: Ch.1 #5, 7, 16, 18, 24, 26, 29 Ch.18 #4, 5, (24), 26, 28, 35, (73, 85) Problems in (parentheses) are not available on eGrade. Hand them in separately? I will post solutions after class Thus. Phys 18 HW 2 due next Thus: Ch.18 # (27), 29, 32, 33, (94), 52

  9. PSE bill

  10. Finish Calculus Ch.1 • PIQ • Trigonometry review • Polynomials

  11. Calc 1 HW 2 Calc 1 HW 2 1.4 # 1, 2, 9, 11, 14, 18, 26, 35 1.6 # 2, 4, 14, 28 Next Thus: Calc 1 HW 3 1.5 # 1, 10, 14, 16, 20, 29, 31, 34, 36 1.6 # 8, 18, 23

  12. Looking ahead • Seminar in Sem II C2109 tonight • Please put your team’s best Q on the board before 5:00 • Friday: Weekly energy essay due • Next week: • Monday: Clean Energy Fair- Sem II courtyard • Telescope: noon between Lab I and LabII • 3:00 – class will go hear speaker • Tuesday: Biodiesel debate • Tutor on Wed.1-3 and Fri.10-12
