Lab Report (30 points possible) Name and Title : (1 point) Rohan nana, Mr. Jeckel , 2-22-18, sound in the sea lab report Objective(s) : (2 points) To describe how the temperature of water affects sound and to demonstrate how dissolved particles scatter around. Hypothesis : (2 points) If the temperature of the water is raised then the frequency of the water will be higher. Procedure : (5 points) Fill four mugs with warm, cold, soapy, and coffee water, and tap the sides of them and see how many rings are formed, and listen to the pitch and record it in a table and repeat the process 3 more times. Independent variable- the temp of the water Dependent variable- the speed of the sound] Control- the amount of water Data : (7 points) warm high high high cold medium low medium coffee low low low Soapy low low low Conclusion : (13 points) My prediction in the beginning of the experiment was correct and supported by the chart above. When I tapped the side of the mug of the warm water the pitch and the number of rings were high. I also found out that when filling the mug with coffee created a minute amount of frequencies. Also, the soapy water

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
