Final answer:
Liquid oxygen (LOX) will vaporize into a gaseous state at -100°F.
Step-by-step explanation:
Liquid oxygen (LOX) will vaporize into a gaseous state at extremely low temperatures. The correct answer is A. -100°F. At this temperature, oxygen transforms from a liquid to a gas because the vapor pressure of oxygen exceeds the atmospheric pressure.
This is an example of a substance undergoing sublimation where it directly changes from a solid or liquid to a gas without passing through the intermediate liquid state.
