In countries nearer to polar region, the roads are sprinkled with CaCl ₂ . This is

Options

  1. Ato minimise the wear and tear of the roads
  2. Bto minimise the snow fall
  3. Cto minimise pollution
  4. Dto minimise the accumulation of dust on the road

Correct answer

A. to minimise the wear and tear of the roads

Step-by-step solution

In countries nearer to polar region, the roads are sprinkled with CaCl ₂ because CaCl ₂ decreases the freezing point of ice and therefore, minimise the wear and tear of the roads.
