Answer (1)
5. Each of the following containers is airtight and has the same number of molecules. Which container has the highest pressure?Answer: The container with the smallest volume (highest compression) has the highest pressure.Based on Boyle’s Law (P₁V₁ = P₂V₂), pressure increases as volume decreases if the number of molecules and temperature remain constant.6. Each of the following containers has the same size. Which of the following containers has the most compressed gas molecules?Answer: The container with 4 moles of gas (option "A").The more gas molecules (moles) in the same volume, the higher the gas compression.7. All the gas samples have the same temperature and mass. In which of the following conditions will the gas sample have the highest density?Answer: (A) 10 atmDensity (d) is proportional to pressure (P), so the gas at the highest pressure (10 atm) will have the highest density.8. What happens to the density of a gas as its volume decreases at constant pressure and temperature?Answer: (B) IncreasesSince density = mass/volume, decreasing volume while keeping mass constant results in increased density.9. What law explains the mechanism of a gas compressor?Answer: (A) Boyle's LawBoyle’s Law states that pressure and volume are inversely proportional (P₁V₁ = P₂V₂), which explains how gas compressors work by reducing volume to increase pressure.10. What gas law best explains the explosion of a heated aerosol container?Answer: (D) Ideal Gas Law (PV = nRT) or Gay-Lussac’s Law (P₁/T₁ = P₂/T₂)When temperature increases, pressure increases, potentially leading to an explosion if the container cannot withstand the pressure.11. What gas law explains the relationship among volume, pressure, temperature, and the number of moles of gases?Answer: (C) Combined Gas LawThe Combined Gas Law (P₁V₁/T₁ = P₂V₂/T₂) integrates Boyle’s, Charles’, and Gay-Lussac’s Laws to describe the relationships among pressure, volume, and temperature.
