Kelvin

Kelvin is a unit of measurement for temperature. It is one of the seven base units in the International System of Units (SI). The Kelvin scale is an absolute temperature scale, meaning that it starts at absolute zero, the theoretical point at which the motion of particles ceases.

Key Points to Remember:

1. Kelvin is the base unit of temperature in the International System of Units (SI).
2. The Kelvin scale is an absolute temperature scale.
3. Absolute zero, the lowest possible temperature, is 0 Kelvin.
4. The symbol for Kelvin is K.

Study Guide

Here are some important things to remember about Kelvin:

Definition:

Kelvin is the SI base unit of temperature. It is defined based on the triple point of water, where water exists as a solid, liquid, and gas simultaneously.

Absolute Zero:

Absolute zero, the lowest possible temperature, is 0 Kelvin, and no particle motion occurs at this temperature.

Conversion:

To convert from Celsius to Kelvin, add 273.15 to the Celsius temperature. The formula is: K = °C + 273.15.

Usage:

Kelvin is commonly used in scientific and engineering applications, especially in fields such as physics, chemistry, and astronomy.
