The Energy Definition defines the term ‘energy’.
A definition of the term is based on the basic science of how the energy in a substance is stored, transmuted, or generated.
This definition has been used by chemists and physicists for over 200 years.
When the CEN I was first published in 1960, it was used in chemistry textbooks and in many medical textbooks.
The definition was a bit different to the current one.
In 1960, a person was defined as an individual who had the ability to produce energy from one substance (in this case, the oxygen in water) or another (in the case of energy).
In 1970, it changed to a person with the ability of producing energy from any one substance.
The current definition of energy is based only on the scientific evidence that we have available today.
Today, the definition is updated every year to reflect the new knowledge of how we measure the different forms of energy.
The energy definition for the human body was originally published in 1976, in the American Journal of Medicine.
In 2012, the term was revised to reflect new scientific evidence from the World Health Organization (WHO).
CEN II defines the definition of an individual as an adult with a physical condition that affects the ability, awareness, and/or behaviour of a person to use or manipulate the natural environment in a way that affects their health, well-being, and quality of life.
In 2018, the WHO published a report that included updated scientific evidence.
In 2020, the current version of the definition was updated to reflect updated scientific knowledge from the International Agency for Research on Cancer (IARC).
The new definition of human body energy was developed by the IARC in 2018, and it incorporates the updated scientific information.
CEN III defines the definitions of two aspects of energy: thermal energy and electrical energy.
Thermal energy is the amount of energy stored in a physical body as a result of the movement of the body.
Electrical energy is energy that comes from the electric current flowing through the body, which is stored in the body tissues, muscles, and joints.
Cens IV is used to define human body temperature and the ability or capacity of the person to regulate body temperature.
The definitions are based on information from the latest scientific literature and are updated annually.
This article provides more information about the definitions and how they are used by the WHO.
