Question

, Recording the time it takes (in seconds) for the temperature to drop in increments of 2ºC:

Temperature(°C)	Time(in second)
2ºC	00:52.82
2ºC	00:53.94
2ºC:	00:64.48
2ºC:	00:67.44
2ºC:	00:68.34
2ºC	00:79.83

1, You will treat temperature as if it were a concentration (of heat). In order to analyze the data, you will need to know the difference between each temperature value recorded and the original room temperature. For each temperature value recorded, determine the difference between the temperature of the hot water and the room temperature. T (temperature as concentration) = TH2O - Troom Record this difference in your data table.

Answer 1

Let the room temperature be 30 (°C)

Temperature(°C)	Time(in second)	Temperature of hot water(°C)	TH2O - Troom(°C)
2ºC	00:52.82	=68-2 = 66	=66-30 = 36
2ºC	00:53.94	=66-2=64	=64-30=34
2ºC:	00:64.48	=64-2=62	=62-30=32
2ºC:	00:67.44	=62-2=60	=60-30=30
2ºC:	00:68.34	=60-2=58	=58-30=28
2ºC	00:79.83	=58-2=56	=56-30=26
