What does the ideal gas law (PV=nRT) describe? The diffusion of gas molecules. The kinetic energy of particles. The behavior of real gases. The relationship among pressure,volume , temperature, and moles.

The ideal gas law $(PV=nRT)$ describes the relationship among pressure (P), volume (V), temperature (T), and moles (n) of an ideal gas. It provides a mathematical relationship between these variables, allowing us to predict the behavior of gases under different conditions. The ideal gas law assumes that the gas molecules do not interact with each other and occupy no volume, which is a good approximation for gases at high temperatures and low pressures.
