Calorie (Nutritional)
A calorie (Cal) is a unit of energy used to measure the amount of energy provided by food and beverages, specifically representing the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie was first introduced in the 19th century as a unit to quantify energy in nutrition. It has since become a standard measure in dietary and nutritional contexts, although the scientific community often prefers the joule as the SI unit of energy.
Current Use
Calories are widely used in nutrition to quantify the energy content of food and beverages, helping consumers manage dietary intake and energy balance. The term 'Calorie' with a capital 'C' typically refers to kilocalories (kcal), which are equivalent to 1,000 small calories.
Electron-Volt
An electron-volt (eV) is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing atomic and subatomic energies, especially in quantum physics and particle physics, replacing larger units like the joule for small-scale energies.
Current Use
The electron-volt is widely used in physics and chemistry to quantify energies at the atomic and subatomic levels, such as in spectroscopy, particle physics, and quantum mechanics, due to its convenience in expressing small energy values.
