Exothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Endothermic reactions take in energy and the temperature of the surroundings decreases.

\( Kinetic \ energy = \frac{1}{2} \times mass \times velocity^{2}\) ...

Do not attempt to perform this demonstration. The combustion of methane is an example of an exothermic reaction. More energy is released when the bonds in the products are formed than is used to break ...

Climate change poses grave risks to humanity; confronting it will require a massive transformation of the world’s energy systems. Fossil fuels like oil and gas still shape global geopolitics and ...
