At what expansion ratio does propane gas expand when exposed to heat?

Propane gas is known for its significant expansion when it changes from a liquid to a gas. Under standard conditions, when propane vaporizes, it can expand to approximately 270 times its original liquid volume. This is an essential characteristic that informs safety protocols regarding the storage and handling of propane, particularly because it can lead to explosive hazards if not properly managed.

Recognizing the expansion ratio is crucial for those working in rescue operations or any other field involving fuel gases. Understanding the behavior of propane under heat ensures that proper measures are taken to prevent dangerous situations, such as over-pressurization in storage tanks or unintentional ignitions.

The other ratios, while they may seem plausible, do not accurately reflect propane's expansion under typical conditions, making the 270 to 1 expansion ratio the correct choice in understanding how propane behaves when exposed to heat.
