True or False: An LP container stores propane solely as a vapor?

The correct response is that an LP container does not store propane solely as a vapor; rather, it generally stores propane in both liquid and vapor states. This occurs because propane, like many other liquefied gases, exists in a liquid state under pressure within the container. When the pressure is released, such as when the propane is used or when the valve is opened, some of the liquid converts back into vapor.

Thus, stating that an LP container holds propane only as a vapor is false. The presence of liquid propane is essential for delivering gas efficiently, as the vapor is produced from the liquid due to a decrease in pressure when the contents are drawn from the cylinder. It is also important to note that the liquid-gas transition is a fundamental characteristic of how propane behaves in pressurized containers.
