| 1 | Ethanol is the more volatile component. | |
| 2 | And water and ethanol are both volatile. | |
| 3 | Because the top is loose, the alcohol inside has volatilized. | |
| 4 | You decrease the mole fraction of the less volatile material in the gas phase. | |
| 5 | Where sugar is clearly the solute, but sugar is not volatile clearly this is a bad example. |
