The specific heat capacity (c) of aluminium, wood, granite, and iron are 0.897 j/c. g, 1.68 j/c. g, 0.790 j/c. g, and 0.450 j/c. g, respectively. if each of these materials is heated with 100 j of energy, which one would heat the slowest? i need to show work as well. you!

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.
