because it probably rained!
Yes but only for about 11 seconds at the very most
Someone can minimize the chances of a wiper arm being detached by making sure some water is sprinkled on the windshield while operating the wipers. The water provides some lubrication for the wipers to move easily.
Road maps are maps that show you the road.
it depends on what kind of weather you are in... but mostly, it's on summers...
They help to displace water to keep your car from Aquaplaning. To get the most friction and therefore the best braking effect, the more area in contact with the road, the better. On a dry road, slick tyres would be best. But if you tried this in the rain you would Aquaplane, when the water would form a barrier beween the tyre and the road and give no grip. So the grooves are only of use on wet roads. It is a legal requirement to have at leasy 1.6mm of tread groove, on tyres in the UK.
the water moves in
nothing, it's only effective when salt is sprinkled ON the ice.
it dies
It Sweats
I do this. It helps to smooth out the wrinkles.
probably because it is cold and it shocks you
Rain and or tap water sprinkled and sunlight
to keep them fresh
Some summers the water for agriculture is not sufficient.
Part of the water evaporates; this cools the water.
because the salt absorbs the water so that it dehydrates and dies
The salt reacts chemically with the water in the snow, lowering its melting point. Depending on outside temp, this may be enough to cause the snow/ice to melt.
