Question

A sample of nitrogen gas is at 37°C (99°F). If heat is removed from the sample, its temperature will and it could undergo a change of state into a
-. (1 point)
• decrease; liquid
• increase; solid
• increase; liquid
decrease; gas

Answer 1

If heat is removed from the nitrogen gas sample at 37°C, its temperature will **decrease**; however, nitrogen remains a gas at this temperature and will only change state at a much lower temperature. Nitrogen will change from a gas to a liquid at around -196°C (-321°F). Therefore, the best choice from your options is:

**decrease; liquid**
