•It rains 100 mm/yr over a landfill that is 2000m2 in size. 50% of the water infiltrates and 50% of the water is runoff. Leachate collects within the landfill and is drained off and treated. Unfortunately, only 90% of the leachate is treated and the rest ends up in the surrounding soil.
•A) Calculate the volume in m3 of water that infiltrates through the landfill each year.
•B) What is the volume in m3 of leachate that is treated each year? Use the previous answer
•C) If the leachate that enters the soil contains 2.0 g/m3 of cadmium, calculate the mass in kg of cadmium that enters the soil per year

Tuesday 2/28/17: (both questions)
•#1---A 100 Watt bulb uses 100 J/sec of electrical energy.
•a) Is all of the energy coming to the light bulb used to produce light?
•b) If the bulb is 20% efficient, then how much energy is being lost? In what form is the lost energy?
•#2---How much energy in kilojoules does a 100 watt light bulb use when it is turned on for 30 minutes? (1 watt = 1 Joule per second)
Wednesday 3/1/17: (both questions)
•#1--How many kilojoules are in one kilowatt-hour? (1 Watt = 1 Joule/sec & 1000 W = 1 kW and 1 kilojoule = 1000 joules)
•#2--If a 100 Watt light bulb is lit for 18 minutes, how many kilowatt hours of electricity did it use?
Thursday 3/2/17:

Tuesday 3/7/17:
•An electric clothes dryer has a power rating of 4000Watts. Assume a family does 5 loads of laundry each week for 4 weeks, and each time the dryer runs it is for one hour. Find the energy used drying clothes in that time in
a) kWh AND
b) Joules (1W = 1 J/sec)
Thursday 3/9/17:
A window air conditioner uses 1000 Watts when it is running. If it is running for 8 hours a day during all of June, July, and August, how many total kilowatt hours will be charged on your electric bill for those three months? And if your electricity rate is 5 cents per kWh, how much are you spending on that one air conditioner?
Thursday 3/16/17:
The average American home used about 11,000 kWh of electricity in 2008. Suppose the electricity in your region was supplied by the burning of natural gas. How many cubic feet of natural gas is needed to support one home? (1ft3 natural gas = 1030 BTU and 1 kWh = 3410 BTU)
Friday 3/17/17: practice questions at the end of the ch 20 powerpoint
#1--A power plant has the capacity to produce 12 megawatts of electricity and the average household consumes 8000 kWh of electricty each year. Assuming that the power plant can operate at full capacity for 8000 hrs/yr, How many kWh of electricity can the power plant generate each year and how many households can that supply electricity for?
#2--Going back to our 1450 Watt microwave (from 3/2):
•1 kWh of electricity is equal to 3413 BTU. One cubic foot of natural gas supplies approximately 1,031 BTU of energy. How much natural gas would be required to power the 1450 Watt microwave for one year (remember it takes 265 kWh as we already calculated)?
