The Ideal Gas Law governs the relationship of which three state variables? (Choose three.)

The correct answer is A. Volume. Volume (A), Pressure (C), and Temperature (E) are the three state variables governed by the Ideal Gas Law, expressed as PV = nRT, where P is pressure, V is volume, and T is temperature (with n as moles of gas and R as the gas constant). Viscosity (B) describes a fluid's…

Explanation

Volume (A), Pressure (C), and Temperature (E) are the three state variables governed by the Ideal Gas Law, expressed as PV = nRT, where P is pressure, V is volume, and T is temperature (with n as moles of gas and R as the gas constant). Viscosity (B) describes a fluid's resistance to flow and is a transport property, not a variable in the Ideal Gas Law. Conductivity (D) refers to a material's ability to conduct heat or electricity and is similarly unrelated to the law. Both viscosity and conductivity describe how a substance behaves or moves, not its thermodynamic state.

Memory tip: Remember the phrase "PVT" (Pressure, Volume, Temperature) - think of it as the trio that defines a gas's condition, and note that PV = nRT has exactly these three on the left and right sides of the equation.
