And the following (tricky!) questions:

Sometimes, on a humid summer night, you'll find condensation (a fine mist of water droplets) on your car windshield.

(a) Does it form on the inside or the outside of the windshield, and why?

(b) You can remove the condensation using your "defroster", which blows air onto the windshield.  Should you use cold or hot air?  Explain carefully how your choice removes the condensation.  ("Evaporation" is not a sufficient answer --- why does evaporation occur here?)

Homework due April 9th: Giancoli Chapter 13

Questions (NOT PROBLEMS) 2,4,8,10,11 [Make your answer as short as possible while making sure it remains clear.]

[For instance, a suitable answer to Question 6 would be: "The pressure inside the can equals atmospheric pressure when the can is sealed, but since the air inside the can is hotter than the air outside, it is less dense..  Once the air inside cools to room temperature, its pressure decreases below atmospheric pressure.  The air outside exerts a greater pressure inward, and crushes the can."]

Problems (NOT QUESTIONS) 7,10,15,23a,33,78,83,90,98

Feel free to email me if you think there is something wrong with one of the problems, such as a typo or ambiguity.
For conceptual physics questions, please come to office hours; email doesn't work very well.
