Essay Assignment - PHYS110 SPRING 2015
A. Topics
1. Write an essay on different temperature measurement devices. Explain the operational principle of each device, its advantages and disadvantages, its cost, and its range of applicability. Which device would you recommend for use in the following cases: taking the temperatures of patients in a doctor's office, monitoring the variations of temperature of a car engine block at several locations, and monitoring the temperatures in the furnace of a power plant?
2. Find out the prices of heating oil, natural gas, and electricity in your area, and determine the cost of each per kWh of energy supplied to the house as heat. Go through your utility bills and determine how much money you spent for heating last
January. Also determine how much your January heating bill would be for each of the heating systems if you had the latest and most efficient system installed.
3. Prepare a report on the heating systems available in your area for residential buildings.
Discuss the advantages and disadvantages of each system and compare their initial and operating costs. What are the important factors in the selection of a heating system?
Give some guidelines. Identify the conditions under which each heating system would be the best choice in your area
4. Solar energy reaching the earth is about 1350 W/m2 outside the earth's atmosphere and
950 W/m2 on earth's surface normal to the sun on a clear day. Someone is marketing
2 m × 3 m photovoltaic cell panels with the claim that a single panel can meet the electricity needs of a house. How do you evaluate this claim? Photovoltaic cells have a conversion efficiency of about 15 percent.
5. Conduct a literature survey that reviews that concept of thermal pollution and its current state of the art.
6. Find out how the specific heats of gases, liquids, and solids are determined in national laboratories. Describe the experimental apparatus and the procedures used.
7. Obtain the following
