Last class we used something new with our robots. We were given a burner, thermometer probes and a beaker of water and a beaker with oil. In the lab we were supposed to heat up the liquids and observe which liquid absorbed the heat energy the quickest. To do that our robots were hooked up to the two probes, which were used to measure the temperature. We first measured the temperature of the liquids without any heat to get a base temperature. We then put the beakers on the burner, placed the probes in the liquid (making sure not to let it touch the glass), and let the program run its course.
Below you can see our results from the lab.
In our lab the temperature change was not what we expected. The oil is supposed to have the highest temperature change, but that was not the case. We also had to calculate the energy absorbed by both liquids, and for our experiment the water absorbed more energy. That was also unexpected, because the oil is supposed to absorb the most energy.
Change in Water | Change in oil | Energy Absorbed by Water | Energy Absorbed by Oil |
4.146799 | 3.614559 | 1388.016561 | 532.0630848 |
We are not sure why our experiment didn’t work out the way it was supposed to. The oil was a higher temperature than the water though, which was supposed to happen, but our other data was off and we really don’t know why. Our probes did not touch the glass, and both beakers were put on the burner at the same time.
