What Does the k mean in melting point of elements?

Answer 1

"K" is short for "Kelvin" - a temperature scale in degrees the same size as Celsius, but whose "0" degrees point is not freezing, but absolute zero - no heat, at all.

The Kelvin scale is handy for scientists because there are no "below zero" or negative degrees. This makes things a lot easier when making scientific calculations.

The term was taken from "Lord Kelvin". His name was William Thompson, and he was a 19th century physicist. His english title was First Baron of (family) Kelvin, or simply, "Lord Kelvin".

Answer 2

The "K" in the melting point of elements represents a unit of temperature measurement called Kelvin. It is an absolute temperature scale where 0 K is absolute zero, the lowest possible temperature where all molecular motion ceases. In this scale, the melting point of elements is often expressed in Kelvins (K) instead of degrees Celsius or Fahrenheit.
