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 lowest possible temperature where particles have minimal motion. In the Kelvin scale, the freezing point of water is 273.15 K and the boiling point of water is 373.15 K.

Unlike the Celsius and Fahrenheit scales, which use the freezing and boiling points of water as reference points, the Kelvin scale uses absolute zero as its starting point. This makes it a useful scale for scientific and engineering calculations, especially in fields such as physics, chemistry, and engineering.

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, starting at absolute zero.
3. The freezing point of water is 273.15 K and the boiling point of water is 373.15 K on the Kelvin scale.
4. Kelvin is commonly used in scientific and engineering applications.

Now that you understand the basics of Kelvin, here are some study questions to test your knowledge:
