Kelvin

Kelvin is a unit of measurement for temperature and is one of the seven base units 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 as the standard unit of temperature measurement.

Key Points to Remember about Kelvin:

1. Kelvin is the base unit of temperature in the International System of Units (SI).
2. The Kelvin scale is an absolute temperature scale, meaning it starts at absolute zero, the theoretical lowest possible temperature where the motion of particles ceases.
3. Water freezes at 273.15 K and boils at 373.15 K on the Kelvin scale.
4. The size of the kelvin is the same as the Celsius degree; the only difference is their starting points.

Study Guide:

Here are some key questions and concepts to help you study Kelvin:

1. What is Kelvin?

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.

2. What is the Kelvin scale?

The Kelvin scale is an absolute temperature scale, starting at absolute zero, the theoretical lowest possible temperature. It is widely used in scientific and engineering fields.

3. How does the Kelvin scale relate to the Celsius scale?

The size of the kelvin is the same as the Celsius degree; the only difference is their starting points. Absolute zero is 0 K, which is equivalent to -273.15 °C.

4. What are the freezing and boiling points of water in Kelvin?

Water freezes at 273.15 K and boils at 373.15 K on the Kelvin scale.

Remembering these key points and concepts will help you understand and remember the important aspects of Kelvin and its significance in temperature measurement.

Good luck with your studies!
