The average density of pure ice is about 920 kg/m³. The average density of seawater is about 1025 kg/m³. By Archimedes's principle, the mass of the seawater displaced (i.e. the amount of the iceberg underwater) should equal the mass of the iceberg.
Using that principle, for each 1 m³ of seawater displaced it takes 1025 kg of ice - which will have a volume of 1025 kg x 1 m³/920 kg = 1.114 m³. In other words, 1m³ of the iceberg is submerged for every 1.114 m³ of iceberg.
1/1.114 = 0.89756
So, on average about 90% of the iceberg is submerged.
If the seawater is a little less salty, more of the iceberg is submerged.
If the iceberg is "dirty" - with stuff in it that is more dense than ice, more of the iceberg is submerged.
If the iceberg has voids (air pockets) it will be less dense and less of the iceberg is submerged.
Freezing rain occurs when precipitation falls as liquid but freezes upon contact with surfaces that are at or below freezing temperatures. This can create hazardous icy conditions on roads and sidewalks.
It might. It depends on what the average temperature is. If it is warmer but still below freezing, then frost can continue to go deeper. Warm temperatures do not CAUSE frost to go deeper though.

During freezing, water temperature decreases as heat is removed from the water, causing the molecules to slow down and eventually form into a solid state. At the freezing point, the water remains at a constant temperature until it has fully solidified into ice.
When a liquid hits it's freezing point (0 Degrees Celsius) the liquid atoms start to crystallize and expand. Thus, creating ice! when the ice melts, the atoms separate again and decrease in size. Thus, liquid! There you go!
Yes
Anywhere the temperature can go below freezing.
Adding sand does not melt the ice, but it improves traction. Adding salt lowers the freezing/melting point, if the temperature is warmer than the new freezing/melting point of the salt/ice mixture then the ice melts. However there is a minimum temperature that this cannot go below, regardless of the salt used, and if the temperature is below this then salting the road does nothing and only sand will help.
I would rather go barefoot on freezing ice. Ice may be uncomfortable and can cause frostbite, but it is less likely to cause serious and permanent damage compared to hot coals, which can cause severe burns.
I usually go for anything below 40
Ice cream does become quite hard when held at the proper freezing temperature.
Frost is ice so stuff cant go through it so its a solid == ==
Different fluids have different freezing and boiling points. Water has its freezing point at 0 degree Celsius while saline water has its freezing point at -67 degree Celsius.
under the ice is concrete. nothing can go in or out. the temp keeps the water frozen to create a thick layer of ice to skate on
If the temperature does not go below freezing then you're fine. Usually during a snowstorm, it doesn't go below freezing. However, if the water was still in your radiator and also in your engine without antifreeze and the outside temperature did drop below freezing, then you could potentially have a cracked block and/or a cracked radiator on your hands. Usually it's not too bad if the temperature doesn't go too far below freezing, but frozen water expands with a huge amount of force when it gets around 15-20 below zero.
In the winter, when the temps go below freezing, there should not be any water in a car. It should be antifreeze, actual windshield wiper fluid, etc.... This will prevent any freezing.
Is it below freezing when this happens? Maybe there's water in lock and it's freezing. Even if it's not below freezing, have you tried spraying some wd40 into the key hole? There's actually better stuff to squirt into the key hole...look for a product that contains graphite and try that. If below freezing, I've also seen people use a cigarette lighter to heat up there key and then insert the key, wait a few seconds for the heat to melt the ice and then try turning the key.
