What does the term "Vaporization" refer to in LP gas?

The term "Vaporization" in the context of LP gas specifically refers to the conversion of liquid LP gas into a gas. This process occurs when liquid propane, which is stored under pressure in a tank, is exposed to lower pressure or higher temperatures, allowing it to evaporate and change into a gaseous state.

Understanding vaporization is crucial for the proper handling and usage of LP gas because the gas must be in a vapor form to be ignited and used for heating or fueling appliances. In practical applications, as liquid propane is released from a storage tank and experiences a reduction in pressure, it transforms back into a vapor, which can then be transported through pipelines and combusted safely for energy.

The other options describe different phenomena related to LP gas, but they do not accurately define vaporization as it pertains to the transition from liquid to gas.
