The materials necessary for this experiment are: four plastic cups numbered 1-4, a scale, six ice cubes, cold deionized water, a pipet, a heat lamp, two LabQuests, four temperature sensors, some paper towels, and four partners in total. The first thing you will need to do is use the tare function to zero out the mass of cup #1, then add three ice cubes to the cup. Record the mass of the ice cubes. Once the mass is recorded, add cold deionized water to the cup until the total mass is between 99.80 g and 100.20 g. Use the pipet to add and subtract water as needed. Put cup #1 aside when this is accomplished. Repeat this process for cup #2. Continuing to cup #3, use the tare function to zero out the mass of the cup and then add between 99.80 …show more content…

Repeat this process for cup #4. Now place cups #2 and #4 in a secure position where they are not affected by the heat lamp. After that, place cups #1 and #3 under the heat lamp with about 10 cm of space between the lamp and the cups-the heat lamp should remain off for the time being. Once the samples are situated, turn on the LabQuests and attach two temperature sensors to each LabQuest, every partner should be assigned a temperature sensor and a cup. When everyone is ready, they should begin gently stirring the contents of their assigned cup with their temperature sensor, the whole group should try to start stirring at the same time. Continue to stir at a constant rate for the rest of the experiment. The green arrow on the screen of both LabQuests needs to be clicked in order to begin recording data, the heat lamp should be turned on at this point. Carry on measuring the temperature of all four samples until the ice in cup #2 melts completely and the temperature has warmed to a few degrees above 0° C. Once this has happened stop recording data on both LabQuests by clicking the red square on the screen. After this is done turn off the heat lamp and double click on the graph title on the screens of both LabQuests to add a descriptive title to the
