The heating value of a Gas is 39MJm-3
a) If 4.5m-3 of the gas is burned how much energy is released?
b) If the gas is burned in 5 minutes what is the power?
c) If the burning occurs in an engine that converts the energy to forward
motion and the engine is 20% efficient in converting the heat energy: what is
the kinetic energy a vehicle would have after burning the above quantity of
gas? – (assume no losses due to friction or air resistance)
