    well the heat is a byproduct of the combustion, which in turn expands the gases and creates the work. in my mind, either way the heat is part of the work...technically the heat is what expands the gases and creates the work so i'd say B

    Im 14 years been in the business for 2 and 1/2 years now. Have 20 clients and loving the industry. I for sure have ran into some bumps but keeping my head held high and will get threw it. Plan on going to trade school for carpentry and also invest in the relastate. I know a decent amount of carpentry being my dad owns a property business and i work for him in the winter. Cant complain life is good just cant wait to get my schooling done.

    sounds like your still in high school...piston means go to college! get a degree and a job where you don't get your hands dirty! Nothin wrong with liking the industry, but you can go alot farther in it with a college degree and still be well connected and get people to do the dirty work for you. Landscape architecture, Arborist, Horticulture, all would be good degrees if you enjoy the industry. Let me tell ya life changes big time after high school, it ain't all fun and games out in the real world when the bills really start coming in

    But ya cant have combustion without heat.
    So obviously it's a trick question!
    I'd have to go with E. Nunya.
