HW. be sure to have read 5.1 and start looking at 5.2, we will be jumping into the calculations next class.
for the lab please answer the following questions (this will be turned in/checked off in the grade book) no need to type it up though, it is due next class.
-alcohol on gauze, Why did you see the temperature change you saw? describe any heat transfer in terms of system and surroundings.
-melting ice, describe the heat transfer that took place between the water and the ice. Also using the text or your notes from last year try to determine mathematically the amount of heat that was used to melt the ice.
-heating water, how much heat energy was needed to cause the temperature change you measured (find the appropriate equation and constant(s) in the text.
Also I will be typing up a summary of the changes with regard to assessment structure for the class as we discussed so you will be getting that shortly.
Also I have added a new resource to the resources page, an interactive IB chem syllabus you might find useful.
