Answer to Question 1

ANS: D
Oxygen expands to 860 times its liquid volume at 25 C and 1 atm; therefore, the total volume of gaseous oxygen available can be calculated by multiplying the number of liters of liquid oxygen by 860.

Answer to Question 2

ANS: B
The fractional distillation of liquid air creates pure liquid oxygen. There are no by-products from this method. Oxygen concentrators take in room air and separate oxygen from nitrogen.
