Find a heuristic for estimating the compression ratio for a multi-stage compression.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

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.
