Homework for Pd 7 ONLY

Below is the data table and 4 conclusion questions for Lab 9. Since we didn't get to them today in class, the students were asked to answer them for homework. On Thursday, I will be collecting the Hot Finger Cold Finger Diagram, the temperature measurements for Lab 9 and these conclusion question answers. This will be the final batch of grades for the year! How times flies!

Questions:

Question #5:  In this experiment, what determines the amount of heat energy transferred to the samples?

Question #6:  In this experiment, what determines the size of the temperature increase in the water samples?

Question #7:  Does the 200gr of sand that received 24 Moches (4 Candles) of heat energy respond the same as the 200gr of water that also received 24 Moches (4 Candles) of heat energy?  If the sand responded differently than the water did, explain how the response was different.

Question #8:  What do you think people mean when they say ‘heat up’ in sentences like:

                      “It’s heating up outside.”                           or

                      “Let’s heat up the pizza in the oven”      or

                      “Heat up the water with two candles.”
