## Temperature Scales

One the the basic quantities in science is temperature, which is a measure up of the average amount of power of motion, or *kinetic energy*, a system contains. Temperatures space expressed utilizing scales that use units dubbed degrees. There space three scales used for report temperatures. Figure \(\PageIndex1\) compare the three temperature scales.

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

Note the the Kelvin range does no use words *degrees*; a temperature the 295 K is spoken of together “two hundred ninety-five kelvin” and not “two hundreds ninety-five degrees Kelvin.”

Example \(\PageIndex2\): Room Temperature

If the typical room temperature is 72.0°F, what is room temperature in levels Celsius and 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 recognize the temperature in the Kelvin scale:
