Hello I am doing a physics lab report and I am very confused. the lab is on "What is the relationship between mechanical energy and heat?"

procedure

1) Construct a table like the one below to record your data: 2) Pour the water into the beaker. Use the thermometer to measure the temperature of the water. Make sure that it is at room temperature (about 25C). Record this value in the temperature column in your table at time 0 min. 3)Place the egg beater in the water and beat the water at a steady rate for 2 minutes. Quickly record the final temperature of the water. 4)Repeat procedure step 3 four more times. Make sure that you begin the next 2-minute period of beating quickly, to prevent the water from cooling off.

Data

Time of Beating (min) Temperature of Water (C)
0 22.0
2 24.0
4 25.5
6 27.5
8 29.0
10 30.0

Q) Make a lab report including: problem, hypothesis, procedure, manipulated variable, controlled variable, responding variable, observations, analysis, and conclusion.

Q) Many people turn on a fan when they find the air in a room too hot. Based on your findings, what effect does running a fan have on the air in a room? Explain.

Q) Using your data, draw a graph of temperature as a function of the time you used the egg beater. Q) What is the shape of the line of best fit of your graph? What does this shape indicate about the relationship between the time of beating and the temperature of the water? Q) Which of the variables on the graph corresponds to the mechanical energy applied to the system? Q) Which of the variables on the graph corresponds to the heat gained by the system?

Q) Based on your graph, explain the relationship between the mechanical energy applied to the system and the heat gained by the system

Q) Does the experiment prove your original hypothesis? If not, modify your hypothesis to fit the results of your experiment
