1) You have a 134.0g sample of water at -30 oC and you heat it until you have gaseous water at 140 oC. Calculate the energy required for this process

2) Gasoline currently powers the majority of automobiles in the U.S. but electric cars have been touted as a way to reduce our dependence on gasoline as well as improve our air quality by reducing production of byproducts associated with gasoline combustion. Right now gas costs approximately $4.00 per gallon and electricity costs approximately $0.0818 per kilowatt-hour (kWh). (1 watt (W) = 1 J/s and 1 watt-hour (Wh) = 3600 J). Assume that gasoline is comprised of pure octane (C8H18) and is combusted with pure O2 at constant pressure. How much would you spend on electricity to obtain the same amount of energy as you would get by burning one gallon of gas?
