Question

Nitrogen has a melting point of -210 degrees Celsius and a boiling point of -195 degrees Celsius. Your sample of nitrogen is being stored at a temperature of -225 degrees Celsius. In what phase is your sample of nitrogen?

a. Solid
b. Liquid
c. Gas

Answer 1

At -225 degrees Celsius, nitrogen would be in its solid phase, as this temperature is below its melting point.

Step-by-step explanation:

If nitrogen has a melting point of -210 degrees Celsius and a boiling point of -195 degrees Celsius, then at a temperature of -225 degrees Celsius, nitrogen would be in its solid phase. This is because -225 degrees Celsius is lower than both the melting point and the boiling point of nitrogen, indicating that it is in the solid state where the temperature is not high enough to induce a phase change to liquid or gas.
