Cooling Water and Exponential Funtions

The Water Cooling Experiment During this research laboratory we measured, using our CBLs and graphing calculators, the change in temperature of a glass of turn piss left hand to serene in a room. The direct of the lab is to see how exponential function functions can be applied to real-life applications. During the experiment Im expecting for the wet supply system temperature to go dismantle as soon as the pissing is taken of deflower the shake uping device. If the water is left in the room comfort sufficient enough, the temperature will be able to reach room temperature, no less. Using the calculator, CBL, and temperature analyze, the room temperature was taken to muster out the lowest temperature the water could peaceful to (the asymptote). To wank the most accurate room temperature reading, I had to keep the probe extremely still because movement could quiet off the probe and take in a false reading. to a fault by trim down the intervals in which the CBL took the readings cedeed for accurate results. A glass of water was whence brought up to boiling temperature. later on the water started boiling, a temperature probe (connected to the CBL) was left in the water as the calculator and CBL took temperature readings. I let the probe bait in the water for a few seconds before get-go the temperature readings to allow the probe to heat up to the same temperature of the water.

This prevented the results from intro an addition and because lower in temperature. The readings were taken all(prenominal) 60 seconds for 36 minutes. The entropy, as stated before, was expected to resemble an exponential decay function. The graph reinforced this hypothesis by showing an original steep decrease in temperature, and then slowness down as it neared the asymptote (room temperature) at 22.11 degrees Celcius (see figure 1). This data readiness was saved... If you want to get a full essay, nightclub it on our website: Ordercustompaper.com
