Temperature Scales

One that the an essential quantities in scientific research is temperature, which is a measure up of the median amount of power of motion, or kinetic energy, a device contains. Temperatures space expressed utilizing scales that use units referred to as degrees. There are three scales provided for report temperatures. Figure \(\PageIndex1\) to compare the 3 temperature scales.

For most purposes, the is agree to use 273 rather of 273.15 in Equation \refC2K.

Note the the Kelvin range does not use the word degrees; a temperature of 295 K is spoken of together “two hundred ninety-five kelvin” and also not “two hundred ninety-five levels Kelvin.”


Example \(\PageIndex2\): Room Temperature

If the regular room temperature is 72.0°F, what is room temperature in levels Celsius and also kelvin?

Solution

First, we use Equation \refF2C to determine the temperature in levels Celsius:

\<\beginalign* ^\circC &= (72.0-32)\times \dfrac59 \\<5pt> &= 40.0\times \dfrac59 \\<5pt> &= 22.2^\circC \endalign*\>

Then we usage Equation \refC2K to identify the temperature in the Kelvin scale:
