What state of matter has the most kinetic energy

Gas

Explanation:

since the gas molecules arent being forcefully bonded together like a solid would be, and liquids tend to have lower kinetic energy than solids

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.
