I’m looking at the butter package as I have my breakfast. It says that a 1 tbsp serving weighs 14 g and has 100 Calories of energy content. You are to estimate the energy content “per gallon of butter” and compare it to another hydrocarbon fuel…namely gasoline. Gas has combustion energy content of about 10 kWh per liter. Use the common unit of kWh per gallon as your comparison unit. Which is more energy rich?

A 3000 kg car goes from 0 to 70 miles per hour in 6 seconds. Assume all the work supplied by the engine goes into increasing the kinetic energy of the car. 1. If the engine is purely electrical (and 100% efficient), determine the electrical work supplied in kW.h by the engine battery. A kW.h of electricity costs about 25 cents (this is just for your information). (kWh) 2.If the engine is a gasoline powered engine, determine the fuel consumed...

2000 pounds (50 bags) of wood pellet fuel costs $249 in bulk from Home Depot, Lowe’s, or Tractor Supply. In our part of the country, it is not uncommon to burn about 2.5 pounds of wood pellets an hour during the six months of peak home heating needs. At 2.5 pound/hour rate of consumption, how many pounds of wood pellets would you use each day? How many pounds of wood pellets would you need for 183 days of heating? What...
