Phase changes, vapor pressure and colligative properties
Main lesson
Vapor pressure of a solution
Use this for “0.5 mol of glucose is dissolved in 9.5 mol of water at 25 °C. How much does the vapor pressure drop?”
What moves the boiling point?
Use this for “Why does an egg take longer to cook in boiling water high on a mountain?”
Phase changes: heat in or heat out?
Use this for “Is freezing endothermic or exothermic?”
