What are Arithmetic and Geometric Sequences? A sequence is a group of numbers, called terms, arranged in a specific order. Arithmetic Sequences. Arithmetic sequences have a common difference. In other words the same value is added or subtracted from term to term. Example: 1, 3, 5, 7, 9, 11 (common difference is +2)
The Kelvin temperature scale is useful because scientists around the world use it as a temperature scale so that they don't have to convert Celsius to Fahrenheit or vise versa â¦ .
The Kelvin scale is an absolute, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.n 1848, Lord Kelvin wrote in his paper, On an Absolute Thermometric Scale, of the need for a scale whereby infinite cold (absolute zero) was the scale's null point, and which used the degree Celsius for its unit increment.
