Measuring Physical Properties Lab Report Instructions: In the Physical Properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in Tiny World. Record your observations and test measurements in the lab report below. You will submit your completed report. Name and Title: , instructor's name, Sep 9th, measuring physical properties lab report. Hypothesis: In this section, include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment. If we use Aluminum to build the roof of the house, then the temperature inside the house will remain cooler. If we use Clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler. If we use copper to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate. If we use Iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure. Procedure: The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using the summary questions, clearly define the dependent and independent variables of the experiment. Independent V- The type of material tested. dependent V- The results of each test completed Objective(s): In your own words, what was the purpose of this lab? Conclusion: Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words. 1. Using two to three sentences, summarize what you investigated and observed in this lab. 2. What building material did you use to build your house? Did your results support or fail to support your hypotheses? 3. What were the densities of the materials you chose for the walls and floor for the home in Tiny World? Why do you think a building material's density is important when building homes or architectural structures? 4. Why wouldn’t you choose wood or aluminum for the latches on your house? 5. Which material has the highest thermal conductivity? Which material has the highest electrical conductivity? Explain why thermal and electrical conductivity is so high with this material. 6. Think about where you live now or where you have lived in the past; use complete sentences to describe this environment and the weather. What building materials do you believe would work well to build a home in that area? Explain why you chose these materials. P.S. Answer objections and conclusion.

The electrolyte that is used to make Hypochlorous Acid is made from Sodium Chloride (NaCl). the bottle says that the electrolyte solution contains 25% sodium chloride. If 2.4 ounces of the solution is added to the half gallon to prepare for the reaction. How many total grams of sodium chloride are used in the reaction. If the reaction produces 1100 PPM of HOCl (hypocholorus acid) how many grams of Hypocholrous are made? Do you think all the NaCl was converted to HOCl? or we can brew one more time and get more HOCl. If all of the NaCl converts to HOCl what would be the maximum possible PPM of the disinfectant
