Question: What happens to gases when pressure is increased?
Answer: Compress
Explanation: Gases can be compressed by increasing pressure as their particles have large intermolecular spaces.
Question: What state of matter is formed when a gas is compressed under high pressure?
Answer: Liquid
Explanation: Under high pressure and low temperature, gases condense into liquids.
Question: What is the process of converting a gas into a liquid by applying pressure?
Answer: Liquefaction
Explanation: Liquefaction occurs when gases are subjected to high pressure and low temperatures.
Question: What is the term for the stored gas in a compressed form?
Answer: Liquefied gas
Explanation: Gases like LPG and CNG are stored in compressed liquid form under high pressure.
Question: Which gas is commonly stored in cylinders under high pressure for cooking purposes?
Answer: LPG
Explanation: Liquefied Petroleum Gas (LPG) is stored in cylinders for domestic and industrial use.
Question: What is the process of changing a solid into a gas by reducing pressure?
Answer: Sublimation
Explanation: Some solids directly convert into gas when pressure is reduced, bypassing the liquid state.
Question: Which gas is stored under high pressure in vehicles for fuel purposes?
Answer: CNG
Explanation: Compressed Natural Gas (CNG) is stored under high pressure and used as a fuel alternative.
Question: What happens to the boiling point of a liquid when pressure is increased?
Answer: Increases
Explanation: Higher pressure raises the boiling point by preventing molecules from escaping as gas.
Question: What happens to the boiling point of a liquid when pressure is decreased?
Answer: Decreases
Explanation: Lowering pressure allows molecules to escape more easily, reducing the boiling point.
Question: What is the instrument used to measure atmospheric pressure?
Answer: Barometer
Explanation: A barometer is used to measure atmospheric pressure, which affects boiling points and weather conditions.
