Heating The amount of chemical potential energy stored in one gallon of heating oil is approximately 130 MJ. This is the amount of energy released as heat during combustion. (Note: 1.0 kWh = 3600 kW-sec = 3600 kJ = 3.6 MJ. Verify this equivalency and use it to answer the following question.) a. Suppose that during the winter, heating your home with oil may require an average of 6 gallons of oil per day. Assuming that to be the case, what is the average daily energy consumption? (Express your answer in kWh.) b. If the cost of heating oil is $3.00/gallon, what is the daily cost to heat your home? Use this information to find the cost of heating with oil in units of cents/kWh.
Problem 2: This problem compares the energy output and heat transfer to the environment by two different types of nuclear power stations—one with the normal efficiency of 36 %, and another with an improved efficiency of 47 %. Suppose both have the same heat transfer into the engine in one day, 2.5 × 1014 J Part (a) How much more electrical energy is produced by the more efficient power station? Part (b) What is the change in the heat transfer to the environment after the upgrade to the more efficient power station?
The first law of thermodynamics relates the heat transfer into or out of a system to the change of internal and the work done on the system. How much heat, in joules, is transferred into a system when its internal energy decreases by 165 J while it was performing 27.5 J of work?
