Propane released into the air expands to about how many times its original volume?

Explanation:
Propane stored in a cylinder is a liquid under pressure, and when it’s released it quickly vaporizes into a gas at ambient temperature. That liquid-to-gas change means the volume expands dramatically—about 270 times its original liquid volume under typical conditions. Because of that large expansion, a small amount of liquid propane can produce a very large invisible gas cloud in the air. Since propane is heavier than air, this cloud tends to hug the ground and spread with air currents, posing a serious fire or explosion risk if there’s a source of ignition. This huge expansion factor is why this fact is emphasized in safety training: even a tiny liquid leak can become a sizable, potentially dangerous gas cloud.
