7. Draw conclusions - Interpret the data from the graph made in Question 7. What conclusions can you make based on the results of this graph?

1. Use the graph below to predict what the results will look like if the null hypothesis is

6. Although you are basically satisfied with the analysis thus far, you are concerned about the

1.What two factors did you investigate in your procedure, and why did you choose to compare these two factors?

Present all relevant data in a data table below. Include an observations section for any observations you made during the lab. Make sure you note the data needs to be converted before graphing.

You have the mass of water from calculation #9, the specific heat of water is 4.184 J/g(oC), and the temperature change of water

6. Restate your predictions that were correct and give the data from your experiment that supports them. Restate your predictions

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

In the following discussion of how I performed each task, I will explain the reasoning for my research.

8. The heat energy added as latent heat of melting and latent heat of vaporization does not increase water temperature. Explain why this occurs and where the energy is used.

1. Using the data set currently posted inside DocSharing, perform the hypothesis test for each of the above situations in order to see if there is evidence to support your manager’s belief in each case a.-d.  In each case use the Seven Elements of a Test of Hypothesis, in Section 6.2 of your text book with α = .05, and explain your conclusion in simple terms.  Also be sure to compute the p-value and interpret.

Q7: Create a bar graph or pie chart of the data you have collected. For example, you could create a bar graph that shows the employee turnover rate in organizations that do offer flexible work arrangement compared to organizations that do not. Alternately, you could create a pie chart that shows which types of flexible work arrangement workers want the most.

I then recorded down my results working out an average and efficiency; put this data into a table and a graph. Before reaching my conclusion.

An increase in internal energy is required to convert a solid to a liquid,. Conversely, a reduction in internal energy can cause liquids to freeze or solidify. When heat is added to a solid or a liquid, the temperature of the sample does not necessarily rise. During a phase change, heat is added to the sample without an increase in temperature. Heat absorbed or released as the result of a phase change is called latent heat. There is no temperature change during a phase change, thus there is no change in the kinetic energy of the particles in the material. Latent heat is an intensive

The following findings were carried out after analysing the data in the light of given objectives:
