When stored under pressure, butane is in ______ form.

When stored under pressure, butane is in ______ form.

• A. Gas
• B. Plasma
• C. Liquid
• D. Aerosol

Answer: (C)

When a gas is compressed and kept at room temperature, it can condense into a liquid. Butane is a gas at room temperature and atmospheric pressure, so storing it under high pressure causes it to become a liquid inside the container. This liquid form allows compact storage and high energy content; when you release the pressure through a valve, the liquid rapidly vaporizes back into a gas to provide the usable fuel. The other options don’t fit because you’re not storing butane as plasma or as tiny droplets in a gas (aerosol), and under pressure it doesn’t remain in its gaseous form.
