Back 1

1. turn on
2. Main Menue
3. Temperature (F2)
4. Temperatuer vs. Time (F1)
5. Fill beaker with ice & water
6. Calibrate (0.0; enter)
7. Swirl till it gets as close to 0 (enter)
8. SetUp

Correction Factor

Back 2

Temp probe- cool water
thermometer- warm water
place both is 50ml of room temp water
subtract thermometer from probe

Front 3

Determining Calorimeter Constant

Back 3

1. get 2 styrophom cups
2. Weigh them
3. add 50 ml of water and weigh again (find mass of water)
4. set up stirrer and temp probe
5. obtain beaker and weigh
6. heat water, weigh again, and measure mass of water
7. measure initial temps of water (correct the thermometer)
8.start, add water to cup (wait a few secs)
9.let temp reach equilibrium, press stop

Re-plotting

Back 4

1. set up
2. re-plot (F2)
3. change
4. display
5. save (file options, F3)

Calorimeter equation

Back 5

-(mct)cool - (mct)warm

take answer and divide by chance in temp of cool water
