Question

How many cubic feet of gaseous oxygen at atmospheric pressure will one cubic foot (7.5 gallons) of liquid oxygen (LOX) expand to?

A. 80 cubic feet
B. 160 cubic feet
C. 240 cubic feet
D. 320 cubic feet

Answer 1

Liquid oxygen (LOX) expands to approximately 160 cubic feet of gaseous oxygen at atmospheric pressure.

Step-by-step explanation:

Liquid oxygen (LOX) expands to approximately 160 cubic feet of gaseous oxygen at atmospheric pressure. When a liquid changes to a gas, it undergoes a process called vaporization. During vaporization, the substance absorbs heat energy and expands in volume. In the case of liquid oxygen, one cubic foot of LOX expands to approximately 160 cubic feet of gaseous oxygen when it is vaporized.
