Water can convert into ice by:, increasing temperature, decreasing temperature, applying pressure, Silver fused at :, 303C, 327C, 500C, 961C, at the triple point :, T and P are constant, T and P most change together, T and P change dependently, T and P change independently, For a pure gas Degree of freedom is:, F=2, F=0, F=1, F=3, solution of ethanol and water has :, p=1, C=2, S=2, all of above, a system consisting of two / more phases called :, physical state, heterogeneous system, homogeneous system, pure substances, ice in water have:, p=4, p=1, p=2, p=3, Phase : state of matter that is uniform throughout both in ———————— and physical state ., homogeneous system, chemical composition, color, degree of freedom, how to predict the phase boundaries in one-component , two-phase system:, use Clapeyron equation, use first low of thermodynamics, use Graps law, Chemical potential depends on:, Temperature., pressure., pressure,Temperature, If the enthalpy of fusion is positive the slope will depend on the, pressure, temperature, molar volumes, The slope of the phase boundary line well be in water case, Zero, Negative, positive., In most common cases the molar volume of the solid is.........of the liquid, less, greater, equal, polymorphism is, same substance, more than one crystalline forms, answer (أ),(ب), different substance, supercooling is, stable condition, unstable condition, not equilibrium state, gas.
