Astudent lives in a place that receives lots of snow and ice during the winter. the student has observed that the highway department spreads salt on the road after a snowfall. which of the following correctly explains why the highway department uses salt on the roads? salt lowers the freezing point of water, which makes the melted snow on the road less likely to form ice. salt raises the freezing point of water, which makes the melted snow on the road less likely to form ice. salt raises the vapor pressure of water, which makes the melted snow more likely to evaporate before it freezes. salt lowers the osmotic pressure of water, which makes the melted snow more likely to be absorbed into the ground before it freezes.

When a solute is added to pure solvent, the freezing point of the solvent is lowered. So in order to reduce the overall freezing point of the solution, salt is added to the ice on the road after a snowfall. Addition of salt results in the melting of ice as the freezing point of ice is lowered than it's freezing temperature, when salt is added to pure solvent. The higher the amount of salt added, lower will be the freezing point of overall solution. Therefore, the correct answer is Salt lowers the freezing point of water, which makes the melted snow on the road less likely to form ice.
