Burning a gallon of gasoline releases 1.19 x 10^8 J of internal energy. If a certain car requires 5.20 x 10^5 J of work to drive one mile how much heat is given off to the atmosphere each mile, assuming the car get 25.0 miles to the gallon? If the miles per gallon of the car is increased, does the amount of heat released to the atmosphere increase, decrease, or stay the same?
