Decomposition in Physics

Decomposition refers to the process in which a complex substance breaks down into simpler substances or elements. This process can occur through various means, such as chemical reactions, nuclear reactions, or even natural processes like decay.

Chemical Decomposition

In the context of chemistry and physics, chemical decomposition occurs when a compound is broken down into simpler substances through a chemical reaction. This can involve the breaking of chemical bonds within the compound, leading to the formation of new substances.

Example:

One common example of chemical decomposition is the electrolysis of water, in which water (H2O) is broken down into its constituent elements, hydrogen (H2) and oxygen (O2), through the application of an electric current.

Nuclear Decomposition

Nuclear decomposition, also known as nuclear decay, occurs when the nucleus of an atom undergoes a spontaneous transformation, resulting in the emission of radiation and the formation of new elements or isotopes.

Example:

One example of nuclear decomposition is the alpha decay of uranium-238, in which the uranium nucleus emits an alpha particle (consisting of two protons and two neutrons) to form thorium-234.
