Which gas law states the relationship among pressure, volume, and temperature of a gas?
A
Charles's Law
B
Ideal Gas Law
C
Boyle's Law
D
Avogadro's Law
Verified step by step guidance1
Identify the variables involved: pressure (P), volume (V), and temperature (T) of a gas.
Recall that Charles's Law relates volume and temperature at constant pressure, Boyle's Law relates pressure and volume at constant temperature, and Avogadro's Law relates volume and amount of gas at constant temperature and pressure.
Understand that the Ideal Gas Law combines all these variables into one equation, relating pressure, volume, temperature, and amount of gas (n).
Write the Ideal Gas Law equation: \(P \times V = n \times R \times T\), where \(R\) is the ideal gas constant.
Conclude that the Ideal Gas Law is the gas law that states the relationship among pressure, volume, and temperature of a gas.
