Which formula represents the ideal gas law?

The ideal gas law is formulated as ( PV = nRT ), where ( P ) represents the pressure of the gas, ( V ) is the volume it occupies, ( n ) is the number of moles of the gas, ( R ) is the ideal gas constant, and ( T ) is the temperature measured in Kelvin. This equation succinctly describes the relationship between these variables under ideal conditions, where the gas behaves ideally without significant intermolecular forces and occupies a volume with no restrictions.

This formula is vital in understanding the behavior of gases since it allows operators and scientists to predict how gases will respond to changes in pressure, volume, and temperature. For example, if the pressure of a gas is increased while keeping the temperature constant, the volume must decrease accordingly to maintain equality in the equation.

The other options provided do not correctly represent the ideal gas law. For instance, one option misplaces the terms and includes incorrect operations, while another alters the relationship with an incorrect exponent on temperature, which is not supported by the fundamentals of gas laws. Each of these deviations from the correct formulation would lead to inaccurate conclusions in practical applications involving gases.
