Objective
Becoming oriented with the different programs and equipment utilized over the duration of this quarter was the objective. In this lab, a temperature probe and a Vernier Lab Pro computer interface measured temperature data. The Logger Pro Software collected the evidence and created graphs illustrating the information. After transferring the measurements, Microsoft Excel aided in calculating the averages of constant data as well as the standard deviation around the mean. After performing all of the necessary calculations, Microsoft Word assisted in compiling all the relative material into one final report.
Theory
This experiment will test the idea that heat will flow from an area of higher energy to an area of lower energy until the …show more content…

We then got the Logger Pro software up and running on the computer, ready to record data.

Procedure A wanted us to record the ambient air of the room. To make this measurement, we held the thermometer by its plastic handle and allowed the Logger Pro system to record the temperature for 50 seconds. The graph of the data appeared to be a straight line, aside from minor fluctuations, indicating a constant temperature. We then used the data to calculate the number of points (N), the mean (Tavg), and standard deviation (σ) of the ambient room temperature.

Procedure B then instructed us to record the temperature of a student’s hand. To ensure we would get the entire reading, we increased the reading time to 200 seconds. We did not use the entire 200 seconds, but this made sure we wouldn’t run out of time before the temperature reading reached equilibrium. We let the thermometer measure the ambient air for 10 seconds before grabbing the thermometer. The student then held the thermometer until the temperature leveled off for 4-5 seconds. It’s important to note the student shouldn’t adjust their hand grip on the thermometer. This will cause unnecessary fluctuations in the data. This process took 75.5 seconds to complete. We then found the mean temperature, the difference in temperature between the temperature readings and the final temperature of the hand,

Our objective was to pick the best chemical to be used in a hand warm. This chemical had to be cheap, relatively safe, and must raise the temperature by 20oC and no more. We add 6 different chemicals to water we record the inshell temperature and then add one a the 6 chemicals to the water and record the temperature change of the water. We also add cold water hot water together to find how much heat would escape the calorimeter. We found that the calorimeter absorbed 71.1J/oC. Then this information to calculate the energy that was released by all of the chemical reaction.

The first test was to measure levels of dissolved oxygen and temperatures at different depths. The procedure for testing the dissolved oxygen and temperature was carried out using a submersible probe. The procedure consisted of lowering the submersible probe by 50 cm increments deeper and deeper into the lake water off of the dock and taking measurements at each increment. The measurements were then recorded, averaged, and reported to the rest of the class. Another test was taken, but this time it was a sampling of the plankton in the lake water.

“Collect” was clicked to begin data collection. Once the pressure and temperature stabilized in the boiling water bath, “Keep” was clicked. The heating was turned OFF on the hotplate, and ice was added to the bath to cool it. “Keep” was clicked once the temperature of the bath cooled to 95°C. The procedure was continued as the temperature continued to decrease, and “Keep” was clicked at every 5°C increment until the bath reached 0°C.

\tab The purpose of this experiment is to acquire technical skills as well as well as to create a circuit that is able to measure temperature with an analog temperature transducer. After the experiment, the student will be able to answer the following questions. How do you translate a schematic to a resistive circuit on a breadboard? How do you use a multimeter and a DC power supply?

The probe was let to soak in the liquid for thirty seconds. The date analysis was started after thirty seconds and the probe was left in the liquid for five seconds to establish a baseline. After the baseline was established, the probe was pulled out and taped to the table with the end of the probe facing out of the table. The data collection should continue until the graph reaches a absolute minimum. Using the statistics option in the LabQuest probe, a change in temperature will be calculated for each trial.

During the cooler seasons, Virginia gets very cold and thus, the people living in Virginia also get cold. The colder temperatures, not only in Virginia, are the reason for the existence of hand warmers. The experiment conducted was perused for the sole reason of saving money on these said hand warmers. If having more sodium acetate in the hand warmer lasts longer with the highest temperatures than having less sodium acetate, then one would simply buys the bigger hand warmer. After making sodium acetate, the liquid was placed into pouches, which would go on to be tested for their temperatures over a certain period of time.

As mentioned in the hypothesis, the prediction is that as the temperature increases towards the optimal, the rate of respiration will increase. As the temperature exceeds the optimal, the rate of respiration will decrease. The temperature of the environment can be varied by placing the respiration chamber under a temperature-controlled water bath/cooling bath. The temperatures that will be used in this experiment will range from 0ºC to 50ºC in 10ºC increments. Digital thermometer will be used to measure the temperature of air.

Newton’s Law of Cooling tells us that the rate of change of an object’s temperature is proportional to the difference between its own temperature and the surrounding temperature.” He paused to let Watson make sense of what he just said before continuing, “By using the temperature of the room at the murder, the temperature of a live human, and the temperatures of the body as it cooled, we will be able to discover the culprit.” Watson pulled out a TI-84 graphing calculator to calculate as Holmes spelled out the formula and the steps. Holmes summarized, “You plug the original temperature of the room into the equation. Then you need to find the constant and the rate which you can find by using the temperature readings.
