1. You have 1 kg ice (at 0o C) in a well-insulated container. How much boiling water must be added to produce only water at 0o C. Lf 3.33x105 J/kg Lv 2.26x106 J/kg c ice 2090 J/kg·oC water 4186 J/kg·oC steam 2010 J/kg·oC

3. If the ice starts out at -20o what do I change?

4. If the water starts out at as steam at 100o what do I change?

5. Conduction Energy moves but matter does not move Thermal Energy Transfer: Zeroth Law HOT COLD

6. Convection Movement of hot or cold matter Air currents or water currents Energy and matter move Thermal Energy Transfer HOT

7. Thermal Energy Transfer Radiation Long range Electromagnetic waves Visible, Infrared Energy moves but matter does not move HOT

8. First Law of Thermodynamics

9. Work done on the gas

10. Work done on the gas

12. P In the path shown, the work done on the gas is isobaric V • Negative • Positive • Zero

13. P In the paths shown below which process is work the largest (in magnitude)? V • Red • Blue • They are the same

14. P In the paths shown below which process is work the largest (in magnitude)? V • Red • Blue • They are the same

15. P In the path shown, the work done on the gas is isovolumetric V • Negative • Positive • Zero

16. P In the path shown, the work done on the gas is cyclic start end V • Negative • Positive • Zero
