vapor-pressure curve → A graph generated by plotting the temperature of a liquid on the x-axis and its vapor pressure on the y-axis. Any point on the curve represents an equilibrium between the vapor and the liquid.
sublimation → A system of a solvent and one or more solutes homogeneously mixed.
meter → Anything that has mass and occupies space.
solute → The substance that is dissolved in a solution.
hydrogen bond → Mater without a uniform composition-- having two or more components or phases.
