The energy possessed by water in a dam is:
Correct answer: A. Potential energy
- A. Potential energy
- B. Kinetic energy
- C. Electric energy
- D. Heat energy
Explanation
The energy possessed by water in a dam is potential energy.Potential energy is the energy that an object has due to its position or state. In the case of water in a dam, the potential energy is due to the height of the water above the ground. The higher the water is, the more potential energy it has.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
