Kelvin

The kelvin is the base unit of temperature in the International System of Units (SI). It is named after the Scottish physicist William Thomson, 1st Baron Kelvin. The kelvin is used in many scientific and engineering fields, particularly in the study of thermodynamics and the behavior of gases.

Key Points to Remember:

1. The kelvin is the unit of measurement for temperature in the SI system.
2. It is named after the Scottish physicist William Thomson, 1st Baron Kelvin.
3. The Kelvin scale starts at absolute zero, which is the lowest possible temperature where particles have minimal motion.
4. Water freezes at 273.15 K and boils at 373.15 K on the Kelvin scale.

Study Guide:

Here are some key concepts to understand when studying the kelvin:

Absolute Zero:

Understand that the Kelvin scale starts at absolute zero, which is the lowest possible temperature where particles have minimal motion. Absolute zero is 0 K.

Freezing and Boiling Points:

Know that water freezes at 273.15 K and boils at 373.15 K on the Kelvin scale. These points are different from the Celsius scale, where water freezes at 0°C and boils at 100°C.

Applications:

Learn about the various applications of the kelvin in scientific research, engineering, and everyday life. Understand how the Kelvin scale is used in thermodynamics, gas laws, and other fields.

By understanding these key points and concepts, you will have a solid foundation in the topic of kelvin and its significance in the field of science and engineering.
