Kelvin

Kelvin, a unit of thermodynamic temperature that is part of the SI system. Kelvin was defined as 1/273.16 of the temperature at the equilibrium point between water, ice and steam. This unit of measurement is used to measure temperature in various scientific and technological fields such as physics, chemistry, biology and medicine.

Temperature expressed in kelvins (K) is equal to temperature expressed in degrees Celsius (℃) plus 273.15℃. The notation Kelvin (K) is the standard notation in the SI system.

The unit of measurement Kelvin represents the ideal temperature at which the pressure of an ideal gas is equal to atmospheric pressure. This means that at a given temperature and pressure, an ideal gas will be in equilibrium with its environment. Thus, the kelvin is a unit of temperature that is independent of pressure or other environmental factors.

Kelvin is widely used in scientific and technical fields, as well as in everyday life. For example, the boiling point of water is about 100°C and the freezing point of water is 0°C. These values ​​can be expressed in kelvins using the formula:

temperature in kelvins = temperature in degrees Celsius + 273.15.

Thus, Kelvins are units of temperature that are widely used in scientific and technological fields.

Kelvin is a unit of thermodynamic temperature used in the SI system of measurements. It was introduced in 1848 by the British physicist William Thomson (Lord Kelvin) in honor of his father, also a famous scientist.

Kelvin is defined as 1/273.16 of the temperature at the equilibrium point between ice, water and steam. Thus, Kelvin is a measure of the temperature at which all three phases are in equilibrium. This temperature is called the triple point of water and is equal to 0°C.

It is important to note that Kelvin is not a unit of temperature as we are accustomed to understanding it. It is used to measure the thermodynamic properties of substances and systems, such as pressure, volume and entropy.

In the SI measurement system, Kelvin is denoted by the letter K and is equal to 1/273.15 degrees Celsius. This means that if the temperature is measured in degrees Celsius (ºC), then to convert it to Kelvin you need to add 273.15 ºC. For example, if the temperature is 20 ºC, then its equivalent in Kelvin will be 293.15 K.

However, although Kelvin is a unit of thermodynamic temperature and has widespread use in scientific research, it is not the only unit of temperature measurement. Some fields, such as medicine and technology, use other units of measurement, such as degrees Fahrenheit (ºF) and degrees Kelvin (K).

Thus, the Kelvin remains an important SI unit of thermodynamic temperature, but it is not the only way to measure temperature.

Kelvin is a unit of the thermodynamic temperature scale that is used to measure temperature throughout the world. It was introduced at the end of the 19th century thanks to the British physicist William Kelvin, who wanted to unify the temperature of the international system of weights and measures. Kelvin proposed a new unit of measurement for temperature by separating the temperature of the triple point of water as a reference point. This point was chosen because it is the equilibrium point between the liquid, gaseous and solid states of water. The name Kelvin was chosen to honor a scientist who made significant contributions to this field of science and technology.

Kelvin was adopted as the International System of Units (SI) in 1964 and has since been widely used in various fields of science. In the SI system, the kelvin is one of the seven basic units of measurement, along with the meter, kilogram
