How does the density of propane liquid compare to water?

Propane liquid is lighter than water, which is an important factor in understanding its properties and behavior during storage and handling. The density of propane at standard conditions is approximately 490 kg/m³, whereas the density of water is about 1000 kg/m³. This means that when propane and water are mixed, propane will float on top of water. This characteristic becomes crucial in various scenarios involving LP-gas, such as in leaks or spills, where understanding the behavior of the gas can help in implementing safety measures.

Recognizing that propane is lighter than water assists individuals in the LP-gas industry in predicting how propane will behave in different environments and shapes their response strategy in the event of a leak or other hazardous situation.
