Question

In temperature countries, salt is sprayed on raods to defrost and clear roads but the long term effect on this practice is costly to motorist. Explain why the long term effect is costing to motorists

Answer 1

Answer:

Answer: The biggest reason for pouring salt on icy roads is that salt lowers the freezing point of water. Water normally freezes at 32 degrees Fahrenheit, but when you add salt, that threshold drops to 20 degrees (or even 2 degrees) Fahrenheit. ... You can watch as the water surrounding each grain of salt melts.
