1. My responsibilities: 1) Make clear what material you must master 2) Present some of the derivations and applications of physics in class 3) Use clicker quizzes to let you know what the important concepts are 4) Give you opportunities to improve your skills through homework assignments 5) Make problem solving tutoring available through SI and problems course 6) Establish a reward (grading) system that rewards you for hard work, but does not give As when the physics has not been mastered. YOUR responsibilities 1) Read the book 2) Do the homework in a timely fashion, as a responsible adult 3) Review the homework in the proper manner, i.e. without solutions. Re-work the problems! 4) View homework as a means to an end: the end is competence at solving physics problems. 5) SELF assess whether YOU understand the material and can solve problems NO ONE CAN LEARN TO SOLVE PHYSICS PROBLEMS BY JUST WATCHING PHYSICS PROBLEMS BEING SOLVED.

2. Chapter 17 Young&Freedman Some things are hot, some things are cold. Heating (usually) causes expansion. In thermal contact, two objects (eventually) reach the same temperature. Daniel Gabriel Fahrenheit (1686–1736) Fahrenheit temperature: The zero point was determined by placing the thermometer in brine: a mixture of ice, water, and ammonium chloride, a salt. This is a frigorific mixture. 96 degrees, was the level of the liquid in the thermometer when held in the mouth or under the armpit of his wife. Celsius used ice/water and water/steam for 0 and 100.

3. Gases also expand on heating. Demo Kelvin temperature Units: K The ‘size’ of 1K = 1°C

4. What is the approximate boiling temperature of water, in K? A] 100 K B] 212 K C] 273 K D] 373 K E] 485 K

5. Solids also (usually) expand on heating.

6. If I heat this metal annulus, The hole will: A] get smaller B] get bigger C] stay the same size
