Milk is mostly water but with a few additional substances so the boiling point of milk is very slightly higher than that of water. Milk is not a homogeneous substance - the proportions of water and fats vary from cow to cow, from species to species, from pasture to pasture and from season to season. Although milk producers do try to standardise, it is not comprehensive. As a result, there is no exact figure at which milk will boil (at standard pressure). It is likely to by about a 1/4 degrees above 100 deg C.
In general, water with stuff dissolved in it has a lower freezing temperature than pure water. Milk is just water with stuff (fats, sugars, proteins) dissolved in it so it's freezing temperature should be lower than 0 degrees Celsius (the freezing temperature of water).Therefore, if you started with both frozen milk and frozen water at say -10 degrees Celsius and started slowly heating them both, the frozen milk will start thawing (melting) before the frozen water.
water, the density is less Milk normally freezes between -0.53 and -0.56 °C. Water freezes at 0.
Water freezes the fastest among these liquids because it has a higher freezing point than oil, vinegar, and milk. Oil, vinegar, and milk have lower freezing points due to their composition, which means they require lower temperatures or longer freezing times to solidify compared to water.
The freezing point of a solution is the temperature at which the liquid in the solution solidifies or freezes.
At mercury's own freezing temperature, the mercury can be either solid or liquid; that is the definition of "freezing temperature".
I'm not sure I see what you're asking.. Freezing is what happens when I substance gets below it's freezing temperature - the temperature at which it becomes solid.
No, milk typically freezes at around -0.55 degrees Celsius. If the temperature is above that, milk will remain liquid until it reaches that freezing point.
No, cow's milk should not smell after freezing. However, colostrum may have a different smell to it than regular milk. This is just due to the antibodies in the milk, however, milk should not smell any different post freezing as it would pre freezing.
Milk from Jersey cows tends to freeze last as the temperature drops. Jersey cows produce milk with higher fat content compared to other dairy breeds, which helps prevent freezing at lower temperatures. The higher fat content creates a lower freezing point for the milk, allowing it to remain liquid for longer periods in colder conditions.
Water-- any impurities serve to depress the freezing temperature.
Without knowing both the initial temperature of the milk and the temperature of the environment it is in, I cannot do anything but give a meaningless guess. I can assume that milk freezes close enough to the freezing point of water and that the latent heat of freezing is also close enough to water that neither is important (it can be calculated for water and assume the answer for milk is same).
The butterfat in milk basically 'doesnt' freeze, but the water in the milk is allowed to form ice crystals very fast as the butterfat particles move out of the way as it happens - you might have seen this - the milk freezes in thin layers as the butterfat content levels out.
32 degrees Fahrenheit (or 0 degrees celsius) is the point of freezing.
no.
Freezing or thawing does not change weight.

The temperature above freezing is any temperature above 32 degrees Fahrenheit (0 degrees Celsius).
