Question

multiple choice question
which states that the volume of a fixed amount of gas held at a constant temperature varies inversely with the pressure?
○ combined gas law
○ boyles law
○ charless law
○ gay-lussacs law

Explanation:

• Combined gas law relates pressure, volume, and temperature of a gas, not just volume and pressure at constant temperature.
• Boyle's law defines the inverse relationship between the volume and pressure of a fixed amount of gas at constant temperature, expressed as $P_1V_1 = P_2V_2$.
• Charles's law describes the direct relationship between volume and temperature of a gas at constant pressure.
• Gay-Lussac's law describes the direct relationship between pressure and temperature of a gas at constant volume.

Answer:

B. Boyle's law
