Which of the following laws is directly related to the formulation of the ideal gas law?

• A. All of the above
• B. Charles's Law
• C. Avogadro's Law
• D. Boyle's Law

Answer: (A)

Verified step by step guidance

1. Recall that the ideal gas law is expressed as \(PV = nRT\), where \(P\) is pressure, \(V\) is volume, \(n\) is the number of moles, \(R\) is the gas constant, and \(T\) is temperature.
2. Understand that the ideal gas law combines relationships between pressure, volume, temperature, and amount of gas, which are individually described by different gas laws.
3. Charles's Law states that volume is directly proportional to temperature at constant pressure: \(\frac{V}{T} = \text{constant}\).
4. Boyle's Law states that pressure is inversely proportional to volume at constant temperature: \(PV = \text{constant}\).
5. Avogadro's Law states that volume is directly proportional to the number of moles at constant temperature and pressure: \(\frac{V}{n} = \text{constant}\), and combining all these laws leads to the ideal gas law.
