What is the specific gravity of LP gas?

  1. 0.5 - 1.0

  2. 1.0 - 1.5

  3. 1.5 - 2.0

  4. 2.0 - 2.5

The correct answer is: 0.5 - 1.0

LP gas, also known as liquefied petroleum gas, typically consists of propane or butane. The specific gravity of LP gas generally falls in the range of 0.5 to 1.0. This range is indicative of the density of LP gas compared to the density of air (1.0). A specific gravity of less than 1 indicates that LP gas is lighter than air, which is important to consider for safety reasons as it can easily disperse and dissipate in the atmosphere. The correct answer is A because it accurately reflects the specific gravity range typical for LP gas.
