Which gas law relates pressure, volume, and temperature of a gas?

• A. Boyle's Law
• B. Charles's Law
• C. Ideal gas law (PV=nRT)
• D. Avogadro's Law

Answer: (C)

The relationship between pressure, volume, and temperature of a gas is best described by the ideal gas law, represented as \(PV = nRT\), where \(P\) is pressure, \(V\) is volume, \(n\) is the number of moles of the gas, \(R\) is the ideal gas constant, and \(T\) is the temperature in Kelvin. This law encompasses the principles of other gas laws, such as Boyle's Law, which states that pressure and volume are inversely related at a constant temperature, and Charles's Law, which states that volume is directly proportional to temperature at constant pressure. The ideal gas law allows for a comprehensive understanding of the gas's behavior under varying conditions of pressure, volume, temperature, and amount of substance, integrating these key variables into a single equation. It provides a more complete picture than the other laws, which address only specific aspects of the gas's behavior. Avogadro's Law specifically relates the volume of a gas to its amount (number of moles) at constant temperature and pressure but does not encompass how temperature and pressure influence volume on their own, nor does it connect all three parameters in a unified framework like the ideal gas law does.
