In a study, the steam in a steam engine drops in temperature by 300 K to 450 K, and drops in quantity of heat to 850.0 MJ.
a. Assuming that the engine is perfectly efficient, and that it can exert a force of 15.0 kN, how far (metres) can it exert that force over?
b. If a new fuel were used that could release ¼ more heat when burning, what would be the high temperature that the steam would now reach?
I am confused as to what unit I would need to convert what into. Any help?
