heat. The shop keeper showed them two types of cooling equipments—a desert cooler and an all-weather air

conditioner. The desert cooler was much cheaper than the air conditioner. Shelly’s mother wanted to buy the

desert cooler as it was much cheaper.

preferred.

Now answer the following questions:

(i) How does common salt or magnesium chloride (or calcium chloride) help in clearing snow from roads?

(ii) At what temperatures, common salt and at what temperatures, magnesium chloride or calcium chloride is

effective?

(iii) Discuss the damaging effects of these chemicals on the environment and how does the use of potassium

acetate remove these damaging effects?
