When the products of a reaction are hotter than the reactants:

the reaction is exothermic.
the reaction is endothermic.
the reactants lost internal energy.
the change in enthalpy is positive.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

they are all solids.
