Acertain type of ship has two tanks in its engine each tank contains a different type of fuel when the engine turns on the same amount of energy is transferred out of both heels as shown in the diagram below why did fuel 1 change phase but fuel 2 stayed the same? explain what happened to the molecules of both fuels.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
