Which statement is true regarding the properties of propane?

Propane is known for its ability to be easily compressed, which is a defining property of gases in general, especially alkanes like propane. When compressed, propane can be stored in a liquid state under pressure, making it effective for use as a fuel. This property allows for efficient transportation and storage, as liquid propane takes up significantly less volume than gaseous propane.

In contrast, propane is highly flammable, so the statement regarding it being non-flammable is inaccurate. Additionally, propane has a relatively high energy content compared to many fuels, making the assertion about low energy content incorrect. Finally, while propane can exist as a liquid under pressure, it is gas at room temperature in standard atmospheric conditions, making the statement about it being a liquid at room temperature false. Understanding these properties is crucial for safe handling and efficient use of propane in various applications.
