What does the ideal gas law relate?

• A. Mass, volume, and temperature
• B. Pressure, volume, and temperature
• C. Density, pressure, and mass
• D. Temperature, speed, and pressure

Answer: (B)

The ideal gas law relates pressure, volume, and temperature of an ideal gas in a coherent way. It is expressed in the form of the equation PV = nRT, where P represents pressure, V stands for volume, n is the number of moles of the gas, R is the ideal gas constant, and T is the absolute temperature in Kelvin. This law provides a fundamental understanding of how gases behave under various conditions and establishes a clear relationship among the three key properties: if one of these properties changes, it will affect the other two while keeping the number of moles and the ideal gas constant consistent. By understanding the connections outlined in the equation, one can predict how the state of a gas will change with adjustments in pressure, volume, or temperature, which is essential in fields such as thermodynamics and fluid mechanics.
