The electronvolt (eV) is a unit of energy commonly used in the fields of physics and chemistry. It is defined as the amount of kinetic energy gained or lost by a single electron when it is accelerated through an electric potential difference of one volt. This unit is particularly useful for measuring small amounts of energy, such as those encountered in atomic and subatomic processes.
The electronvolt is part of the International System of Units (SI) but is not an SI unit itself. Instead, it is derived from the SI unit of energy, the joule (J). Specifically, 1 eV is equivalent to approximately (1.602 \times 10^{-19}) joules. This relationship allows for easy conversion between electronvolts and joules, making it a versatile unit in scientific calculations.
The concept of the electronvolt emerged in the early 20th century as physicists began to explore the behavior of electrons and other subatomic particles. The term was first used in 1900, and since then, it has become a standard unit in various scientific disciplines, including particle physics, quantum mechanics, and solid-state physics. Its widespread adoption reflects the growing importance of understanding energy at the atomic level.
To illustrate the use of the electronvolt, consider a scenario where an electron is accelerated through a potential difference of 5 volts. The energy gained by the electron can be calculated as follows:
[ \text{Energy (eV)} = \text{Charge (C)} \times \text{Voltage (V)} = (1.602 \times 10^{-19} \text{ C}) \times (5 \text{ V}) = 8.01 \times 10^{-19} \text{ J} \approx 5 \text{ eV} ]
The electronvolt is predominantly used in fields such as:

The therm (symbol: thm) is a unit of heat energy that is commonly used in the natural gas industry. One therm is equivalent to 100,000 British thermal units (BTUs) or approximately 29.3 kilowatt-hours (kWh). This unit is essential for measuring energy consumption, particularly in heating applications.
The therm is standardized under the International System of Units (SI) for energy measurement. It is particularly relevant in countries where natural gas is a primary source of heating and energy. Understanding this unit helps consumers and businesses alike to gauge their energy usage and costs effectively.
The therm has its roots in the early 19th century when the need for a standardized unit of heat energy became apparent due to the industrial revolution. As natural gas became a popular energy source, the therm emerged as a practical unit for measuring energy content, allowing for better pricing and consumption tracking.
To convert therms to kilowatt-hours (kWh), you can use the following formula: [ \text{Energy (kWh)} = \text{Energy (thm)} \times 29.3 ] For instance, if you have 5 therms: [ 5 , \text{thm} \times 29.3 , \text{kWh/thm} = 146.5 , \text{kWh} ]
The therm is widely used in residential and commercial heating systems, especially in regions that rely heavily on natural gas. It is also utilized in energy audits, utility billing, and energy efficiency assessments.
