When propane liquid is warmed, how does its volume change?

Increases by 0.5% for every 10 degrees
Increases by 1% for every 10 degrees
Increases by 1.5% for every 10 degrees
Remains constant regardless of temperature

The correct answer is: Increases by 1.5% for every 10 degrees

When propane liquid is warmed, its volume increases due to thermal expansion. This phenomenon occurs as the temperature of the liquid rises, causing the molecules to move more vigorously and occupy more space. The specific rate of expansion for propane is typically around 1.5% for every 10 degrees Celsius increase in temperature. Understanding this behavior is crucial for RV technicians, especially when dealing with propane systems. If the volume of propane expands without proper allowances in the storage tanks or lines, it can lead to pressure build-up, which poses safety hazards. Proper knowledge of this thermal expansion helps technicians design systems that can accommodate changes in volume due to temperature fluctuations, ensuring safe operation of propane-powered appliances in RVs.
