When liquid ethanol evaporates to form ethanol vapour, there are changes in the arrangement of the particles and the density.
Which of these shows the correct changes?
Space between particles in vapour: smaller than in liquid | Density of vapour: greater than liquid
Space between particles in vapour: smaller than in liquid | Density of vapour: less than liquid
Space between particles in vapour: bigger than in liquid | Density of vapour: greater than liquid
Space between particles in vapour: bigger than in liquid | Density of vapour: less than liquid
