The ideal gas law, expressed as PV = nRT, describes the relationship between pressure (P), volume (V), and temperature (T) for an ideal gas. Here, n represents the amount of substance, and R is the ideal gas constant. Given this law, analyze the provided P-T diagram and convert it into a corresponding V-T diagram.
