Question: How much energy does it take to convert 0 500 kg
How much energy does it take to convert 0.500 kg of ice at 220oC to steam at 250oC? Specific heat capacities: ice, 2.1 J g21 8C21; liquid, 4.2 Jg-1oC-1; steam, 2.0 Jg-1oC-1; ΔHvap = 40.7 kJ/ mol; ΔHfus = 6.01 kJ/mol.
Answer to relevant QuestionsConsider a 75.0-g sample of H2O(g) at 125oC. What phase or phases are present when 215 kJ of energy is removed from this sample? (See Exercise 91.) In 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: ...Use the accompanying phase diagram for carbon to answer the following questions. a. How many triple points are in the phase diagram? b. What phases can coexist at each triple point? c. What happens if graphite is subjected ...Boron nitride (BN) exists in two forms. The first is a slippery solid formed from the reaction of BCl3 with NH3, followed by heating in an ammonia atmosphere at 750oC. Subjecting the first form of BN to a pressure of 85,000 ...The high melting points of ionic solids indicate that a lot of energy must be supplied to separate the ions from one another. How is it possible that the ions can separate from one another when soluble ionic compounds are ...
