Unformatted text preview: mol. The ∆ H fus for mercury is 2.33 kJ/mol. How much heat is needed to heat 10.5 g of Hg from -50.0 ˚C to +50.0 ˚C? 6. The vapor pressure of 10 mL of water at 25 ° C is (Greater than//equal to// less than) 20 mL of water at 25 ° C. 7. The boiling point of water in Denver (the mile-high city) is (Greater than//equal to// less than) the boiling point of water in Los Angeles. 8. The phase diagram for benzene (C 6 H 6 ) is shown below: a) Label the solid, liquid, gas, and supercritical fluid regions. b) What physical state exists at T = 150 o C, P = 6 atm? c) Indicate on the graph where the triple point and critical point would be found. d) Describe the change in physical state in going from points A to B to C to D. e) Will solid benzene melt when pressure is applied? Why or why not? Support your answer with evidence from the phase diagram. olid L iquid as Super critical fluid Tr iple Pt Critical Pt...
