What is the ideal gas law equation?

• A. PV = k
• B. P = nRT
• C. P = V/nRT
• D. PV = nRT

Answer: (D)

The ideal gas law is represented by the equation PV = nRT. In this equation, P stands for pressure, V represents volume, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature measured in Kelvin. This law describes how the pressure, volume, and temperature of an ideal gas are interrelated. When you consider a gas under ideal conditions—where it behaves predictably based on the number of moles, temperature, and pressure—this equation helps predict how changes in one parameter affect the others. For example, if you increase the temperature of a gas while keeping the volume constant, the pressure will rise proportionally. The other options do not accurately encapsulate the relationship described by the ideal gas law. While some have individual components related to gas behavior, they do not combine them correctly into the holistic equation that describes the relationship among pressure, volume, amount, and temperature for an ideal gas.
