Which of the following are TRUE statements regarding evaporation, boiling, and vapor pressure? Select as many as are applicable however Select one or more: The vapor pressure at dynamic equilibrium in a closer container does not depend on the amount of liquid, as long as some liquid is always present The vapor pressure at dynamic equilibrium in a closed container depends on the surface area of the liquid The normal boiling point occurs when the vapor pressure of a compound equals 1 bar As a liquid is boiling, its temperature will not change It is impossible for a liquid to evaporate below its boiling point The standard boiling point occurs when the vapor pressure of a compound equals 1 bar The rate of evaporation at temperatures below the boiling point is dependent on surface area

What is the difference between evaporation and condensation? Define each. Boiling point determination can be used for several purposes. What are those purposes? What effect on the boiling point is produced by: (a) a soluble non-volatile impurity, such as table salt (b) an insoluble foreign substance, such as sand A liquid "X" has a normal boiling point of 75 °C. What will be the approximate boiling point of the liquid at 800 mmHg pressure?
Calculate the amount of heat released (in kilojoules) when 68.0 g of steam at 124°C is converted to a solid at a solid at 20° Assume Cs of H2O (s) is 2.09 J/g °C, 4.184 J/g °C over the entire liquid range and C, steam is 1.99 J/g °C, AHmelting = 6.01 kJ/mol and AHvap = 40.67 kJ/mol (Remember AH is a state function) -2840 kJ -3047 kJ +3047 kJ -3.047 kJ 2.840 kJ +2840 kJ
