This lab was to test the change of heat of the water by burning a chip. The energy in the chip was the independent variable and the change in water temperature was the dependent variable. We first had to find the energy in the chip. We lit the chip on fire and found the temperature change in the water. We then had to design a calorimeter to try to improve the energy capture of what we had done before.

Kinetic energy is the energy of motion and potential energy is energy due to an objects position. The energy from either of the kinds of energy cannot be created or destroyed. The ability of to do work is also energy. The Law of Conservation of Energy is that if two systems are doing work together, whatever energy they start with, they have

It comes in two different forms: as a wave and as a particle. As a wave it has many different forms: radio waves, microwaves, infrared waves, visible light, ultraviolet, X-rays, and gamma rays. Waves can be very long and very short and that affects the frequency. When the waves are long the frequency is small and when the waves are short the frequency is high. Electromagnetic radiation interacts with matter in the visible light spectrum because if we didn’t have the radiation reacting with the matter, we would just see in black, white, and …show more content…
The kinetic energy is made from the burning of the chip, we saw the electromagnetic radiation in visible light by the flame, and the calorimeter caught the kinetic energy that came from the chip burning. We also figured out that a calorimeter works best of it is containing the heat all the way around it and not just sitting on top of the beaker. My group had the lowest amount of joules caught with the calorimeter, as seen in figure 2, 7.62% joules captured. Then group 4 captured 12.9% joules, followed by group 1 with 13.39% joules, and with the most was group 3 which caught 21% caught. So in this lab, we were able to show how to make a calorimeter and how it works. There could’ve been many errors in the lab. There could’ve been blunders, human error, and instrumental limitations. The blunders that could’ve occurred when doing the lab were that we could’ve measured the water wrong. The human errors that could’ve occurred during the lab were spilling the water when transferring the water from the graduated cylinder to the beaker. The instrumental limitations we had were that we couldn’t precisely measure the water because we are in a high school lab and not a professional
