Why is salt sprinkled on snow-covered roads in hilly areas to aid in clearing them, and what phenomenon is responsible for this process?

Options

  1. ASalt increases friction between tires and snow, aiding traction.
  2. BSalt lowers the freezing point of water, causing snow to melt.
  3. CSalt absorbs sunlight, accelerating snow melting.
  4. DSalt chemically reacts with snow, breaking it down into water and minerals.

Correct answer

B. Salt lowers the freezing point of water, causing snow to melt.

Step-by-step solution

Correct Option is : (B) Salt lowers the freezing point of water, causing snow to melt.
