4. In many countries with cold climates, the municipalities often sprinkle salt on icy roads in winter.
Which among the following is the correct reason for this?
[A] The Salt inhibits the formation of Ice Crystals
[B] The Salt lowers the Freezing Point of water
[C] The Salt raises the freezing Point of water
[D] The salt provides necessary friction to the tires of the vehicles
Show Answer
Correct Answer: B [The Salt lowers the Freezing Point of water ]
Notes:
The correct reason for sprinkling salt on icy roads is that “the salt lowers the freezing point of water.” This process is known as freezing point depression. When salt (sodium chloride) is added to ice, it disrupts the formation of ice crystals, causing the ice to melt at lower temperatures. This is why salt is commonly used in winter road maintenance. it helps to keep roads safer by preventing ice formation. In fact, salt can lower the freezing point of water to about -9.5°C (15°F) when used in sufficient quantities.
