In regions with dry climates, evaporative coolers are used to cool air. A typical electric air conditioner is rated at 1.00 × 104 Btu/ h (1 Btu, or British thermal unit, equals the amount of energy needed to raise the temperature of 1 lb of water by 18F). How much water must be evaporated each hour to dissipate as much heat as a typical electric air conditioner?
Answer to relevant QuestionsIn each of the following groups of substances, pick the one that has the given property. Justify each answer. a. highest boiling point: CCl4, CF4, CBr4 b. lowest freezing point: LiF, F2, HCl c. lowest vapor pressure at 25oC: ...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? Some water is placed in a sealed glass container connected to a vacuum pump (a device used to pump gases from a container), and the pump is turned on. The water appears to boil and then freezes. Explain these changes by ...Argon has a cubic closest packed structure as a solid. Assuming that argon has a radius of 190 pm, calculate the density of solid argon. For each of the following pairs, predict which substance would be more soluble in water.
