Which of the following phenomena does NOT involve the application of gas?

• burning fuels

• falling leaves

• vulcanizing tire

• rising hot air balloons

Jane can still pump air in the party balloon even though it is already inflated. What explains this phenomenon?

• Balloons look better if its bigger size

• Balloons are made up of plastic

• The air inside the balloon is hot

• Air molecules can be compressed

Which of the following samples is highly compressible at high pressure and expandable at high temperature?

• oxygen gas

• aluminum sheets

• water

• ice

What do you expect to happen to the volume of a gas if its pressure increases at constant temperature?

• Its volume also increases

• Its volume decreases

• Its volume is doubled

• Its volume remains unchanged

Which of the following best describes Boyle’s Law?

• At constant pressure, the volume of as gas in directly proportional to its temperature.

• At constant pressure, the volume of as gas is inversely proportional to is temperature.

• At constant temperature, the volume of a gas is directly proportional to its pressure.

• At constant temperature, the volume of a gas is inversely proportional to its pressure
