What is the specific gravity of propane liquid?

The specific gravity of propane liquid is approximately 0.504. Specific gravity is a measure that compares the density of a substance to the density of water, which has a specific gravity of 1. Propane’s specific gravity being significantly less than 1 indicates that it is less dense than water. This is important in applications where propane is used, as it affects how propane interacts with other substances and how it behaves in different environments.

When considering the alternatives, 1.0 would imply that propane has the same density as water, which is not accurate. Similarly, 0.75 and 0.900 suggest densities that are closer to that of water, which does not reflect the true characteristics of propane. Therefore, the specific gravity of 0.504 most accurately represents the physical properties of liquid propane, making it the correct choice.
