Substances like krypton, which is a gas at room temperature and pressure, can often be liquified or solidified only at very low temperatures. At a pressure of 1 atm, does not condense to a liquid until –153.2°C and does not freeze until –157.1°C. What are the equivalent absolute temperatures?

The boiling and freezing temperatures of krypton at absolute scale are 119.95 K and 116.05 K, respectively.

Explanation:

The absolute temperature on SI units corresponds to Kelvin scale, whose conversion formula in terms of the Celsius scale is:

Where:

- Absolute temperature, measured in Kelvins.

- Relative temperature, measured in Celsius.

Finally, freezing and boiling temperatures are converted into absolute scale:

Boiling temperature

Freezing temperature

The boiling and freezing temperatures of krypton at absolute scale are 119.95 K and 116.05 K, respectively.
