Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules. This energy is released when a chemical reaction takes place.
What is chemical energy 7th grade?
chemical energy: Energy that is stored in the chemical bonds of molecules. This energy is released during chemical reactions. Often, gravitational energy (a form of potential energy) is converted to kinetic energy to make things move fast.
How do we use chemical energy in everyday life?
In power houses chemical energy is converted into electrical energy. Explosives – as explosives go off, chemical energy stored in the explosive is transferred into sound energy, kinetic energy, and thermal energy. Storage batteries – They contain chemical energy which is converted into electrical energy.
Does a phone use chemical energy?
When you plug in a cell phone to charge, for example, the current from the outlet in the wall is converted to chemical energy by the battery inside the device. When you unplug the phone and use it, the chemical energy in the battery is converted back to an electrical charge to power the phone.
Which source of energy is renewable?
