How cold for how long will it take for just water to freeze in a car?
Ok, this is based on equations 0 degrees Celsius is freezing and water will freeze at zero Celsius, but the time to freeze in direct relationship to volume so depending on your vehicle it would take anywhere to 4-6 hours at zero degrees Celsius. For every degree below 5:1 ratio -1 degrees Celsius the 2.5-4.75 hours to freeze. At -20 1 hour or less, to crack the block 2-3 hours. -40 degrees Celsius would take 22 min to freeze and to crack the block 1:10.
How long does it take for cold water to freeze?
It all depends on the temperature of the air that it is in contact with, the air has to be at least 0 degrees Celsius so you cannot work out how quickly it will freeze without knowing the air temperature ;)
What does water freeze on the Celsius scale?
0 degrees Celsius, or 32 degrees Fahrenheit
Why does salt water freeze below 0 celsius?
Salt candissolve ice, so the salt in sea water act like a antifreeze. Sea Water would probably start freezing at - 15C
Can you freeze pineapple?
You can freeze anything with water in it. Pineapple does have water, so if you drop the temperature low enough, it will freeze.
Can dew get frozen?
Dew is water and water can freeze. So yes, dew can freeze.
If salt water freezes does the salt freeze to?
If the salt is still in the water it will freeze inside the water so its technically frozen
Why doesn't achohol freeze?
It does, but its melting (and thus freezing) point is much lower than that of water so you can't actually freeze it in a regular freezer. To be precise, the melting point of ethanol is around -115 degrees Celsius or around -174 degrees Fahrenheit.
What happens to water at minus 20 degrees?
Water freezes and becomes ice at zero degrees Celsius. Also, water has the odd quality that it begins to expand below about 4 degrees Celsius. So the answer is that it would turn into ice and its volume would increase a little.
How do cold air and hot water make the water freeze faster?
Cold air and hot water makes water freeze faster simply because the hot water is steaming and so the result is that there is less water to freeze. hot water = steam = less water less water = faster freeze cold air = faster freeze
How many liters of antifreeze are required in cooling system of peugeot 406?
50 % water to anti freeze mix its about 8 liters in a 406 so 4liters of anti freeze 4 liters of water
Why doesn't ice freeze when you put salt on it?
Ice is already frozen. If it wasn't, we have a different word for it ("water").When you add a solute to anything, it lowers the freezing point (and raises the boiling point, but we're not concerned about that right now). The amount is characteristic of the substance in question ... for water, it's about 1.8 degrees Celsius per mole of solute species per kilogram of water. Table salt dissociates in water to two ions (sodium ion and chloride ion), so adding one mole of table salt (about two ounces) to a kilogram of water (about a quart) will lower the freezing point by around three and a half degrees Celsius. Please note that the water will still freeze if you get it cold enough. Below about -25 or so Celsius, it's impossible to dissolve enough salt in water to keep it from freezing.
