Here are the essential concepts you must grasp in order to answer the question correctly.
Ideal Gas Law
The Ideal Gas Law is a fundamental equation in thermodynamics that relates the pressure, volume, temperature, and number of moles of an ideal gas. It is expressed as PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin. This law assumes that gas particles do not interact and occupy no volume, making it applicable under ideal conditions.

Combined Gas Law
The Combined Gas Law is a formulation that combines Boyle's Law, Charles's Law, and Gay-Lussac's Law into a single equation. It expresses the relationship between pressure, volume, and temperature of a fixed amount of gas, represented as (P1V1)/T1 = (P2V2)/T2. This law is useful for comparing the states of a gas when the amount of gas remains constant, allowing for changes in one variable while observing the effects on the others.

Differences in Application
The primary difference between the Ideal Gas Law and the Combined Gas Law lies in their application. The Ideal Gas Law can be used to calculate the state of an ideal gas under any conditions, while the Combined Gas Law is specifically used to analyze changes in state when the amount of gas is constant. This distinction is crucial for solving problems related to gas behavior in various scenarios.
