For most substances, the solid is more dense than the liquid. Sketch the phase diagram for such a substance, being sure to have the solid-liquid equilibrium line slope in the correct direction. Use Le Châtelier's principle to explain why the melting point of such a substance should increase with pressure. Select all that apply. O An decrease in pressure should favor the system with the lower volume, i.e. the solid. O If melting were to be accomplished at the lower pressure, it would require a temperature that is higher than the normal melting temperature. O An increase in pressure should favor the system with the lower volume, i.e. the solid. O If melting were to be accomplished at the higher pressure, it would require a temperature that is higher than the normal melting temperature. O If the substance is at its melting point at a pressure of one atmosphere, and then if the pressure were to be decreased, more solid would form at the expense of liquid - that is, more of the substance would freeze. O If the substance is at its melting point at a pressure of one atmosphere, and then if the pressure were to be increased, more solid would form at the expense of liquid - that is, more of the substance would freeze.

a) When gaseous water condenses, KMT tells us that the intermolecular attractions cause the slowest of the molecules to aggregate into microdroplets and then into a bulk liquid. Select the statement that is true for this phase change. Phase chang V [Select ] the temperature of the sample, and thus its average Ek, increases the temperature of the sample, and thus its average Ek, is constant the temperature of the sample is directly proportional to the intermolecular attractions. the temperature of the sample descends as the volume of condensed water increases b) Within a associated v b) Within a phase, heat flow is accompanied by a change in temperature, which is associated with a change in average Ek, as the most probable speed of the molecules changes. Select the statement that is true within the phase. V (Select] the molar heat capacity for that phase will change as temperature changes the heat released or absorbed is independent on the amount of substance the heat released or…
