I'm GUESSING none, because at 0 degrees Celsius water begins to freeze and ice begins to melt. No matter how small or how large the amount of water is.

What would be the final temperature when 250 grams of water at 100 degrees celsius is mixed with 525 grams of water at 30 degrees celsius?
The temperature would be that of water's boilng point od 100 degrees
How many grams of KCl remain in solution at 20 degrees celsius when a solution containing 80g of KCl in 200g of water at 50 degrees Celsius is cooled to 20 degrees Celsius?
32 g KCl
What is the mass of potassium chlorate that will dissolve in 50 g of water at 20 degrees Celsius?
Aproximately 4 grams of potassium chlorate will dissolve in 50 g of water at 20 degrees celsius.
What is the enthalpy change for converting 1 mol of ice at -50 degrees celsius to water at 70 degrees celsius?
13.16 kJ
Which will have the greater density water at 40 degrees Celsius or water at -20 degrees Celsius?
Water at -20 degrees Celsius; heat will expand matter, so at +40 degrees Celsius, water would have less density. * * * * * That would be true if there were no phase change. Unfortunately for the above answer, water freezes at 0 deg C and that phase change is accompanied by an expansion. As a result, water at 40 deg C is denser that water (ice) at -20 deg C.
How many grams of sugar must be dissolved in 300 grams of water in order to change the freezing point 2.5 degrees Celsius?

What does water change to above 100 degrees Celsius?
Steam. Water boils at 100 degrees Celsius.
What is the density of water at 20 degrees Celsius-?
What is the density of water at 37 degrees Celsius?
What is the density of warm water cold water and ice?
Density of ice at 0 degrees Celsius is 916.8 grams per cubic centimeter or milliliter. The density of fresh water is dependant on the temperature: At 3.98 degrees Celsius the density is 0.999975 grams per milliliter. At 100 degrees Celsius the density is 0.958.35 grams per milliliter.
What is water at 20 degree Celsius?
It just remains as water. The freezing point of water is 0 degrees Celsius, while the freezing point is 100 degrees Celsius. Therefore at 20 degrees Celsius, there is no change in state and it just remains as water.
How many grams of NaCl can be dissolved in 100g of water at 90 degrees Celsius?
7
Is 250 grams of water the same as 250 millimeter?
That is true when the water is pure and at 4 degrees Celsius.
How many calories are needed to heat up 5 grams of water by 3 degrees Celsius?
(5)(3)= 15 calories. 1 calorie is the energy (heat) to raise 1 gram of water by 1 degree celsius, so 5 grams of water (3 degrees Celsius) = 15.
What state at degrees Celsius does a liquid change into a solid?
it depends on the substance. water freezes at zero degrees Celsius, 32 degrees Fahrenheit.
How many grams of KCl remain in solution at 20 degrees celsius when a solution containing 80g of KCl in 200g of water at 50 degrees Celsius is cooled to 20 degrees Celsius?
32 g KCl
What temperature will water change into ice?
32 Degrees Fahrenheit; 0 Degrees Celsius
