What is the Kelvin temperature scale?

Answer 1

Essentially, it is a temperature scale based on Absolute Zero.

Definition

The Kelvin scale is unique in a few ways from Fahrenheit and Celsius. Primarily, it is based on the measurement of absolute zero. This is a theoretical and highly debated point at which all atoms stop moving (but molecules still vibrate). The scale has no negative numbers because #0# is the lowest Kelvin temperature. When referencing the scale, it is generally best to use K, instead of degrees. For example, water freezes at #273.15# K and boils at #373.15# K.

History

The scale was created by British scientist and inventor William Thomson, who was also known as Lord Kelvin. He was inspired by the discovery of absolute zero in the mid-1800s and also by the Carnot cycle, which is a theory that examines the relationship between work, pressure, and temperature. Thomson's background in mathematics and heat dynamics enabled him to create the scale. His idea was to begin at absolute zero and use the same increments as the Celsius scale to go up from there.

Applications

The Kelvin scale is commonly used in science because it lacks negative numbers, making it useful for recording extremely low temperatures. It is also used in lighting, because of it represents the colour temperature that relates to the physical temperature of some object.

Answer 2

The Kelvin temperature scale is an absolute temperature scale where zero Kelvin (0 K) represents absolute zero, the lowest possible temperature where molecular motion ceases. The scale is based on the theoretical concept of absolute zero, which corresponds to -273.15 degrees Celsius. In the Kelvin scale, temperatures are measured in kelvins (K), with each increment being equal in size to one degree Celsius. The Kelvin scale is commonly used in scientific contexts, particularly in physics and chemistry, where absolute temperatures are required for accurate measurements and calculations.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
