Ared-hot iron nail is immersed in a large bucket of water. although the nail cools down sufficiently to be held bare-handed, the temperature of the water barely increases. which properties keep the water temperature from changing much?

The property of heat conduction is responsible for the heat change in water.

Explanation:Heat conduction is the property of materials in which heat is transfer in the material from hot to cool side by the micro collisions of particles of materials.In this example as rod is transferred in the water the water molecules get energy by the rod and transfer this energy to whole water.Meanwhile the energy of rod lower that is why rod becomes cool to be held by bare-handed.

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
