Consider the following vapor pressure versus temperature plot for three different substances A, B, and C.
If the three substances are CH4, SiH4, and NH3, match each curve to the correct substance.
Answer to relevant QuestionsA plot of ln(Pvap) versus 1/T (K) is linear with a negative slope. Why is this the case? Plot the following data, and from the graph determine ΔHvap for magnesium and lithium. In which metal is the bonding stronger? A 20.0-g sample of ice at 210.0oC is mixed with 100.0 g of water at 80.0oC. Calculate the final temperature of the mixture assuming no heat loss to the surroundings. The heat capacities of H2O(s) and H2O(l) are 2.08 Jg-1oC-1 ...Consider the following phase diagram. What phases are present at points A through H? Identify the triple point, normal boiling point, normal freezing point, and critical point. Which phase is denser, solid or liquid? You have three covalent compounds with three very different boiling points. All of the compounds have similar molar mass and relative shape. Explain how these three compounds could have very different boiling points.
