Question

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

Answer 1

Condenses at 27.25K.

Freezes at 24.65K.

Step-by-step explanation:

In order to solve this above question, there is is need to make use of the following equation. The main idea here is to convert degree celsius to Kelvin. Hence,

0°C + 273.15 = 273.15K---------------------(1).

Therefore, we will make use of the above equation (1) and slot in the values for at degree celsius at which it condenses and at degree celsius at which it freezes.

So, we have at temperature at which it condenses:

-245.9°C + 273.15 = 27.25K.

Also, we have at temperature at which it freezes.

-248.5°C + 273.15 = 24.65K.
