Kinetic energy and potential energy are often considered to be forms of mechanical energy. list three other forms of energy and state a source for each.

Solar Energy: source Sun
Nuclear Energy: source:fission of Uranium nucleus

Sound Energy: source: Loudspeakers

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
