What is the ratio of liquid volume to vapor volume for propane during vaporization?

• A. 100:1
• B. 250:1
• C. 270:1
• D. 300:1

Answer: (C)

The ratio of liquid volume to vapor volume for propane during vaporization is 270:1, which indicates that when propane transitions from its liquid state to its vapor state, one part of liquid propane will produce approximately 270 parts of propane vapor. This high volume expansion during vaporization is characteristic of many liquefied gases and is due to the significant difference in density between the liquid and vapor phases. Understanding this ratio is crucial for propane system design and safety, as it affects pressure and volume calculations in storage and usage. Each of the incorrect options suggests a different ratio, but the precise value of 270:1 is derived from propane's specific physical properties and is recognized in the industry for practical applications such as sizing equipment and ensuring safe handling of the vaporized gas.
