Kelvin temperature scale
Echelle f Kelvin de température

Kelvin temperature scale. Kelvin is the unit of temperature in the International System of Units. Kelvin (K) is similar to Celsius. Absolute zero is 0 K.

Here is a comparison with the Celsius scale:

Kelvin
0
273
310
373
Kelvin

Sazios
-273 Absolute zero
0 freezing point of water
37 Blood temperature
100 boiling point of water
M°

Note: The temperature in Kelvin does not have a sign (°), so the boiling point of water is 373 K.


kerosine
kérosène m

kerosene. One of the products of petroleum refining. It is used as fuel for jet aircraft and household paraffin, which is used for heating, lighting, and boiling kerosene. 160° and 250° C.


kilo. kilo
kilo. kilo

Kilo is a prefix meaning alpha. In general usage, the word kilo has come to mean a kilogram, such as “a kilo of potatoes” (or a kilometer, such as a kilo (101). However, this is an inaccurate expression and should not be used in scientific work.
The uses are:

One kilogram = 1000 grams
One kilometer = 1000 metres
Kilojoules = 1000 joules
One kilowatt-hour = 1000 watt-hours


kilojoule (KJ)
kilojoule m

Kilojoules. A thousand joules.


kinetic energy
Energy in cinema

kinetic energy . Energy possessed by a body as a result of its movement, and the greater its speed, the greater its energy. The kinetic energy of the particle is equal to 1/2, where m is its mass and 7 is its speed. If mass is measured in kilograms and speed in meters/second, kinetic energy is measured in joules.


kinetic theory
Theorie in cinema

Kinetic theory: This theory explains that all particles (atoms and molecules) move and that the extent of movement depends on temperature. The momentum of motion in solids and liquids is limited by the bonds between adjacent particles. There is nothing restricting the movement of gases other than the walls of the container. The higher the temperature, the greater the kinetic energy possessed by the particles. See lattice.


krypton
krypton m

Krypton is a noble gas found in the atmosphere in small quantities and used in electronic valves and fluorescent tubes. Krypton is a monatomic, like all noble gases.
