That would be an ice age.
Obviously, water is deposited on the windshield during the nght and the temperatures drop low enough for it to freeze.
Ugly
Depending on the kind of antifreeze it is, it will freeze at different temperatures. If it is strait antifreeze it will not freeze until very cold temperatures, but if it is 50/50 or if you add water to it, it will have a higher freezing point.
Cold temperatures will, if cold enough, freeze water.
Vietnamese plum survive freeze temperatures
Alcohol does freeze just at lower temperatures. That is why it will not freeze in your household freezer.
Liquids freeze at different temperatures but it is not likely that any will freeze at 100degrees C as that is the teperature at which water boils.
Yes.
Possibly.
A heat pump compressor will freeze if the refrigerant levels are low or the outside temperatures are too low. This will cause the pressure to drop inside the system and temperatures to plummet.
depends on the temperatures
Freezing rain.
