  1. Valentina Tereshkova Becomes 1st Woman in Space (1963) • Reading: Chapter 3 (quiz) • HW #3: DUE Wednesday • 1, 3-7 (all), 11, 13, 17, 18, 21-31 (odd), 39, 45, 49, 50, 51, 56 (only assignment from this chapter) • Dimensional Analysis Homework: DUE Tuesday • Posted on the website • For lab tomorrow (wet lab) • You must have your goggles!!!! • You must have a lab BOOK and lab manual

  2. Conversions It takes roughly 8.317 minutes for the light from the Sun to reach the Earth. If light travels at 2.9979x1010 cm per second, what is the distance in km from the Sun to the Earth?

  3. Conversions It takes roughly 8.317 minutes for the light from the Sun to reach the Earth. If light travels at 2.9979x1010 cm per second, what is the distance in km from the Sun to the Earth? What do I know? 1 s = 2.9979x1010 cm, 1 km = 1x103m, 1 cm = 1x10-2 m, 60s = 1 min

  4. Converting between volumes and areas What is the volume of a 76.31 cm3 container in m3? 1 cm = 1x10-2 m

  5. Converting between volumes and areas What is the volume of a 76.31 cm3 container in m3? (1 cm = 1x10-2 m)3 1 cm = 1x10-2 m  1 cm3 = 1x10-6 m3

  6. Converting between volumes and areas My apartment is 697.5 ft2, how many square miles is it? 1 mi = 5280 ft (1 mi = 5280 ft)2  1 mi2 = 27878400 ft2

  7. Converting between volumes and areas My apartment is 697.5 ft2, how many square miles is it? 1 mi = 5280 ft (1 mi = 5280 ft)2

  8. Conversions Florence Griffith-Joyner holds the women’s 100.m world record, finishing in 10.49 seconds. What was her speed in miles per hour?

  9. Temperature Scales Fahrenheit Celsius Kelvin Boiling Point 212 oF 100 oC 373 K Body Temp 98.6 oF 37 oC 310 K Freezing Point 32 oF 0 oC 273 K

  10. Chemistry:The study of the properties and transformations of matter. Property: A characteristic that can be used to describe a substance. Substances have both physical and chemical properties. Transformations:A change in the properties of matter with time. There are physical changes and chemical changes. Matter: Anything that has mass and occupies space – things you can see, touch, taste, or smell.

  11. Gas Indefinite (variable) shape Indefinite (variable) volume Highly compressible HUGE amounts of space Highly disordered!! Lots of KINETIC energy Low relative density

  12. CONDENSATION!!!!!

  13. Liquid Indefinite (variable) shape Definite (fixed) volume NOT compressible Very little space between More ordered than gas Moderate KINETIC energy High relative density

  14. FREEZING!!!!!

  15. Solid Definite (fixed) shape Definite (fixed) volume NOT compressible Tightly packed Well ordered (organized) Little KINETIC energy High relative density
