That best applies to the alkali metals: lithium, sodium, potassium, rubidium and cesium.
Atomic fusion is the process by which elements which are brought into intimate contact, will undergo fusion, and will form a heavier element, and will emit energy in the process. Much of this released energy is the from the 'binding energy' of the atom.
From heat released when nuclei of uranium 235 undergo fission
radiant energy
Energy is stored in coal through the accumulation of organic materials over millions of years. These materials undergo pressure and heat, transforming them into coal. The energy is stored in the form of chemical bonds within the coal molecules.
Materials that produce heat energy when burned in air include wood, coal, natural gas, oil, and propane. These materials undergo combustion reactions, releasing heat energy as they react with oxygen from the air. The heat energy produced can be used for various purposes, such as heating homes or generating electricity.
Hydration energy (also hydration enthalpy) is the amount of energy released when one mole of ions undergo hydration. It is a special case of dissolution energy, with the solvent being water.
It is a form of potential energy. It turns in Kinetic energy (the energy of movement) when the elastic is released.
Isentropic materials are materials that undergo a reversible, adiabatic process where there is no change in entropy. This means that the material experiences no energy transfer as heat, and its entropy remains constant during the process. Isentropic materials are often used in thermodynamic studies and calculations.
Chemical energy is stored in batteries, food, and other molecules. When these substances undergo chemical reactions, the stored energy is released.
Materials that transfer thermal energy by direct contact better than other materials are called conductors. Conductors have high thermal conductivity, allowing heat to flow through them easily. Metals like copper and aluminum are good examples of conductors.
Friction converts motion energy into heat, sound, and wear or deformation of materials in contact with each other.
Fossil fuels contain chemical potential energy, which is released as thermal energy when they burn. Nuclear fuel which can undergo fission contains energy by virtue of the change of mass which occurs when the nucleus is split into fragments, initially this is released as kinetic energy which is absorbed in the fuel and released as thermal energy.
