Question

Nitrogen has a melting point of -210.0°C and a boiling point of -195.8°C. A sample of nitrogen is heated from -215.0°C to -200.0°C. Which of the following best describes what happens to the nitrogen atoms during this transition?

Answer 1

What are the options?

Answer 2

But without the options I will say at -215 nitrogen is a solid until it is warmed to -210 and undergoes a phase change and turns into a liquid. On the atomic level the atoms go from being in a rigid lattice formations into a loose arrangement where atoms may freely move past one and another.

Answer 3

In liquid Nitrogen there are weak forces between Nitrogen molecules.
