A) if the liquid was cooled to temperature T4, what
phases would be present? what would be the weight % B in each
phase?
B) What would the relative proportions of solid and liquid be at
that T4? please show your work
C) What woud the total weight % of A and of B be in the system
at temperature T2?
Suppose we had a bulk liquid (marked with a red triangle) had a composition of 75% B that underwent...

Chemical potential/phases A substance has three phases: gas, liquid, and solid. The chemical potentials of various phases are illustrated below. T (K) 1) For a given temperature, which of the states represents an equilibrium condition? Submit 2) If the substance starts out in state Q and is held at constant temperature, what happens if it is allowed to reach equilibrium? The substance will freeze. The substance will evaporate The substance will melt and evaporate. The substance will sublime. Nothing...
3. (a) The schematic temperature dependence of the chemical potential of CO2 is given below. Show how the melting pint (TT) will change when increase the pressure and justify your answer. Draw the new u-T line in the following scheme. (b) If this diagram is for water, repeat the same questions in (a). Solid Liquid Chemical potential, Gas Solid stable Liquid stable Gas stable Temperature, T
Paragraph Styles Editing 2 3. Intermolecular forces help dictate various properties of a chemical, draw a representation of a solid, liquid, and gas and describe the intermolecular forces involved. (9 points) 4 Phase Diagrams are useful tools to find if a substance is a gas, liquid, or solid at a certain temperature and pressure. Use the following phase diagram to explain why it takes longer to boil an egg in water at the top of a mountain (hint, what changes...

5. Below you find a sketch of the p,T-phase diagram of H20, indicating preferred physical states of H20 at different temperatures and pressure. The regions labeled with In, XI, and III, stand for different forms of solid H20. For example, ice Ih is the standard ice (there are more than 12 different forms of solid H2O). Draw two diagrams for the chemical potentials as a function of temperature (from Ti to T2) of each of the phases (there are 5...
