Can you use Magnesium sulfate to melt snow?
No. Although technically a "salt", Magnesium Sulfate (Epsom Salt in it's Heptahydrate form) will not melt snow or ice.
How can salt help prevent a buildup of ice on a road?
Salt lowers the freezing point of water up to about -20C or 0F. So water will remain liquid on the salty road surface up to a point. Actually, Fahrenheit himself chose his 0-degree point as the lowest temperature for which water would remain liquid for any amount of dissolved salt in it.
Which melts faster salt water or non salty water?
Salt water freezes at a lower temperature, which is why salt is used to melt road ice. In an environment where the temperature is slowly getting warmer as to melt the ice, frozen salt water will melt quicker than ice.

Why does your mini cooper temperature display flash and a bell ring when the temperature is low?
When the outside temperature reaches 37°F (~3°C), the outside-temperature display on the on-board computer flashes and a chime sounds to alert the driver that the surface of the road may be frozen, therefore possibly slippery, and extra caution should be observed. (Even though ice won't normally occur at 37°F, the temperature probe is several inches above the road surface, and the actual surface temperature may be lower.)

Would a frozen road that has been gritted freeze again?
Short answer yes. Long answer - The salt lowers the temperature at which the mixture freezes. It the temperature were to drop below this the road would freeze again. This temperature varies depending on the concentration of salt. Also if the grit on the road wasn't topped up, it would become diluted and so the temperature required to freeze the road would rise meaning the grit loses it's effectiveness.
Do the fans on your Mazda 323 only work when the engine reaches a certain temperature?

Why does air pressure in a cars tire increase after a long drive?
As you drive, the friction of the road and the flexing of the tire increases the tires temperature. When you increase the temperature of a gas in a sealed container the pressure goes up.As you drive, the friction of the road and the flexing of the tire increases the tires temperature.
