Correct Answer state property (how change is made doesn't matter) Isobaric Isothermal Isometric Adiabatic Correct Answer constant pressure constant temperature constant volume No heat flow A state property, or function, is considered to be what type of differential? Correct Answer Exact Differential Using the calculus rule, how could the following derivative be rewritten as 2 partial derivatives? (dx/dz) at constant y Correct Answer -(dx/dy) at constant z * (dy/dz) at constant x What is an extensive property? Correct Answer property that depends on the size (or extent) of the system under consideration Ex: volume, mass, length What is an intensive property? Correct Answer physical property of a system that does not depend on the system size or the amount of material in the system Ex: temperature, T, refractive index, n, density, ρ, and hardness of an object
