Objectives

After studying the material of this chapter, you should be able to:
1. Convert from joules to calories and kilocalories and vice versa.
2. Distinguish between the concepts of temperature and heat.
3. Explain what is meant by specific heat, latent heat of fusion, and latent heat of vaporization.
4. Apply the law of conservation of energy to problems involving calorimetry.
5. Distinguish the three ways that heat transfer occurs: conduction, convection, and radiation.

Peanut Lab This lab deals with heat and temperature and is teaching students about calories and the differences between calories and food calories. The students create a calorimeter and burn different foods to calculate the number of calories. Most students quickly learn that food calories are kilocalories. They also learn that potato chips, peanuts, and cheetos should all have warning labels "Keep away from flames: Fire Hazard".

• Jump Velocity
• Hint:

PUKE THE LAB before you start.

If Mr. Crane has a vertical of .51M

• What is his hang time?
• What is his jump velocity?
• Is it possible to have a hang time of 1 second?  Draw a diagram with all the important information to illustrate this phenomenon.
• Is it possible to increase your hang time by running first? Explain your reasoning.  How can you test it?

5. How does his reaction time compare to everyone else?  How does everyone else compare to him? Support with numbers and calculations see #3
• Explain how this is possible? 

• Finally- you should have a single page labeled in the back of your notebook and construct a well labeled table of personal information.
• create an entry for your reaction time  and how it compares to the rest of the population
• you should include the date time it was calculated and initial it.
