C. Calculations (Show all calculations with units on each number and the final answer rounded to the correct significant figures for full credit.)Calculate the mass of the water by using the water's density (assume it is 1.00 g/mL) and the volume of the water. Remember, density = mass/volume. (4 pts)Aluminum (Trial 1) – Aluminum (Trial 2) – Calculate the change in temperature for the water caused by the addition of the metal by subtracting the initial temperature of the water from the final temperature of the water. ΔT = Tf - Ti (4 pts)Aluminum (Trial 1) – Aluminum (Trial 2) – Calculate the change in the metal's temperature by subtracting the initial temperature of the metal from the final temperature of the metal. ΔT = Tf - Ti (4 pts)Aluminum (Trial 1) – Aluminum (Trial 2) – Use the equation: q = m(SH)ΔT to solve for the amount of energy gained by the water from metal. Remember to use the specific heat capacity of water in this calculation. (8 pts)Aluminum (Trial 1) – Aluminum (Trial 2) – Use the equation: q = m(SH)ΔT to solve for the specific heat capacity of the metal. For q, you found how much energy was gained by the water so you know that same amount of energy was lost by the metal. Therefore, -qmetal = qwater. (8 pts)Aluminum (Trial 1) – Aluminum (Trial 2) – Determine the percent error using the equation below and the specific heat capacity of the aluminum from the chart provided in the Background Information portion of the lab as the accepted value. The experimental value is your calculated answer for the specific heat capacity of aluminum from Question 5. (4 pts)Aluminum (Trial 1) – Aluminum (Trial 2) – D. Follow-Up QuestionsThe first law of thermodynamics states that energy lost by one object is gained by another. Explain how you used this law to find the specific heat capacity of aluminum. Reference the work you did in Questions 4 and 5. (6 pts)To determine the specific heat of the metal, you assumed that the amount of heat lost by the metal equals the amount of heat gained by the water. Do you think this is a valid assumption? Explain your reasoning and be sure to discuss your percent error for each trial in your response. (6 pts)Were the results of the second trial better than the first trial? Explain why or why not. Your explanation should compare the percent error for each trial and discuss TWO potential sources of error from the procedure (not “human error” or “calculator error”). (6 pts)Why do you think scientists run multiple trials when they are conducting experiments? Discuss TWO potential reasons they would do so. (4 pts)Part II: Identifying an Unknown MetalA. Data Table 2Complete the Data Table. (5 pts)UNKNOWN METALLetter identifying your unknown metal sample (either A, B, C or D)Pre-weighed unknown metal mass (g)Initial temperature of cool water in the calorimeter (oC)Initial temperature of unknown metal (same as the boiling water in the pot) (oC)Final temperature of water/unknown metal in calorimeter (oC)B. Insert the following photo with your name and MEID showing in the photo:Photo B: Insert a photo of your calorimeter showing your unknown metal submerged in water. The photo should be taken from above. (6 pts)C. Calculations (Show all calculations with units on each number and the final answer rounded to the correct significant figures for full credit.)Calculate the mass of the water by using the water's density (assume it is 1.00 g/mL) and the volume of the water. Remember, density = mass/volume. (2 pts)Unknown metal – Calculate the change in temperature for the water caused by the addition of the metal by subtracting the initial temperature of the water from the final temperature of the water. ΔT = Tf - Ti (2 pts)Unknown metal – Calculate the change in the metal's temperature by subtracting the initial temperature of the metal from the final temperature of the metal. ΔT = Tf - Ti (2 pts)Unknown metal – Use the equation: q = m(SH)ΔT to solve for the amount of energy gained by the water from metal. Remember to use the specific heat capacity of water in this calculation. (4 pts)Unknown metal – Use the equation: q = m(SH)ΔT to solve for the specific heat capacity of the metal. For q, you found how much energy was gained by the water so you know that same amount of energy was lost by the metal. Therefore, -qmetal = qwater. (4 pts)Unknown metal – D. Follow-Up QuestionIdentify the unknown metal by comparing the specific heat capacity you calculated in Question 15 to the chart provided in the Background Information portion of the lab. Explain your choice. Be sure to use numerical data related to specific heat capacity to support your claim. (8 pts)

Assignment1.docx It's for this rebric:Assignment 1: Defense in Depth Due Week 4 and worth 70 pointsOftentimes, the process of implementing security opens one’s eyes to other forms of security they hadn’t thought of previously. Well, in this assignment you should experience just that. This assignment focuses on a model of implementing security in layers which in many cases requires a network that is designed accordingly. In this assignment, you are to design a network to incorporate the following: Corporate Site (Chicago)All servers exist here (Web server, file server, print server, mail server, ftp server)Connection to the Internet (50mbps)300 employees who only need access to local corporate resources and the Internet1 Remote Site (8 miles away)20 employees who need access to all resources at corporate  plus the InternetConnection to the Internet (3mbps)Write a four to five (4-5) page paper in which you:Using Microsoft Visio or its open source alternative, design a network diagram, particularly with defense in depth in mind which depicts:All network devices used (routers, switches, hubs, firewalls, VPNs, proxies, and / or others)The interconnections between network devicesThe end user (client) devices (desktops, laptops)The Internet cloud, generically, to represent your network’s interface to the InternetNote: The graphically depicted solution is not included in the required page length.Describe the flow of data through your network, and explain how your network design provides multiple layers of security.Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.Your assignment must follow these formatting requirements:Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.Include charts or diagrams created in Visio or an equivalent such as Dia. The completed diagrams / charts must be imported into the Word document before the paper is submitted.The specific course learning outcomes associated with this assignment are:Explain the essentials of Transmission Control Protocol / Internet Protocol (TCP / IP) behavior and applications used in IP networking.Identify network security tools and discuss techniques for network protection.Use technology and information resources to research issues in network security design.Write clearly and concisely about Advanced Network Security Design topics using proper writing mechanics and technical style conventions.** I can take care of the diagram, don't worry about that, just keep the devices & numbers the same.  thanks
