Answer 1

Step 1: Break down the abbreviation.
LPG stands for Liquefied Petroleum Gas, a mix of hydrocarbon gases, mainly propane and butane, that are stored and transported in liquid form under pressure.
Step 2: Explain how it is used.
When the pressure is released, the liquid turns back into gas, which is then burned as fuel for cooking stoves, heating and some vehicles.
Step 3: Note why it is stored as a liquid.
Storing it as a liquid under moderate pressure lets a large volume of gas fit into a small, portable cylinder, which is why LPG cylinders are common for household cooking gas supply.
Final Answer: Liquefied Petroleum Gas.
