A gas company in Massachusetts charges $2.50 for 15.0ft3 of natural gas (CH4) measured at 20.0 degrees celcius and 1.00 atm. Calculate the cost of heating 200 ml of water (enough to make a cup of coffee or tea) from 20 degrees celcius to 100 degrees celcius. Assume that only 50% of the heat generated by the combustion is used to heat the water; the rest of the heat is lost to the surroundings.
