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?

To convert Celsius temperatures to Kelvin, which is the absolute temperature scale, you add 273.15 to the Celsius temperature. This is because 0 Kelvin is equivalent to -273.15°C, the theoretical point where particles have no kinetic energy.
For krypton's condensation point at -153.2°C: -153.2°C + 273.15 = 119.95 K
For krypton's freezing point at -157.1°C: -157.1°C + 273.15 = 116.05 K
Therefore, the equivalent absolute temperatures for krypton's condensation and freezing points at 1 atm are 119.95 K and 116.05 K, respectively.
