Ice melts at 0 degrees Celsius. That is a speciality of water.
At 3.98 degrees Celsius, the density of water is highest before it begins to form ice crystals. Water at this temperature may be a slush of water and ice.
Ice cream needs to be kept below freezing, because it has ICE in it, and ice needs to be kept at 0 degrees centigrade or lower. On average a fridge is 4 degrees centigrade so it will melt in the fridge...

It is: 0 degrees centigrade that is warmest
4 degrees centigrade is equal to 39.2 degree Fahrenheit.
Because water is heaviest at +4 degrees centigrade, and lighter as ice.
By cooling it below 4 degrees centigrade whereupon its density will decrease. By heating it above 4 degrees centigrade whereupon its density will decrease. Water is at its densest at about 4 degrees centigrade.
39.2 degrees Fahrenheit.
-4ºC = 24.8ºF
No. Most materials expand when they get hotter. A notable exception is water between 0 and 4 degrees centigrade.No. Most materials expand when they get hotter.

At normal atmospheric pressure, water begins to freeze (turn into solid ice) at zero degrees centigrade. ACTUALLY: If saturation occurs at temperatures between 0 degrees Celsius and -4 degrees Celsius , the surplus water vapor invariably condenses into SUPERCOOLED WATER(water having a temperature below the melting point of ice, but nonetheless existing in a liquid state). Ice does not form within this range of temperatures.
Yes, like most substances - above 4 degrees centigrade. From 0 to 4 degrees centigrade, the volume of water will actually decrease while the temperature increases.
1 cc (at 4 degrees centigrade).
Zero degree (if we talk about destilled or reasonably pure water), for sea ice it's typically more around -4 degrees.
The ice melts because the temperature in the refrigerator is above freezing point. This is normal, a refrigerator usually has a temperature of around 4 degrees Celsius.
It will be 20 degree centigrade after 4 hours.
4 degree Celsius = 39.2 degree Fahrenheit.
4 kelvins = -452.47 degrees Fahrenheit.[°F] = [K] × 9⁄5 − 459.67
This is very difficult to answer. At some point the temperature goes above zero degrees. At that point in time it will start to melt. But how long it will take depends on how long the temperature stays near zero, and when it actually reaches 4 degrees. Also, it is possible that such a huge block of ice might still be partially frozen by the time the air temperature reaches 4 degrees. Thick ice on a pond/lake can remain frozen all day even when the air temperature above it has risen above zero.
As things cool, they generally shrink and get more dense. If water continued to shrink and get more dense as it cooled from 4 degrees C, then ice would sink instead of floating, and the ice would eventually freeze the oceans solid. But water begins to EXPAND as it cools from 4 degrees C, and ice forms a crystalline structure that expands as it freezes - so ice floats. That means that when warmer weather happens, the ice can melt.
It is still ice at -4 oC.
SuggestionIf the freezing point of H2O is 0 degrees C, then any temperature over that will start to melt the ice. The more heat, the quicker it will melt. ...it takes 1.67x10^7 Joules...1.67x10^4 KiloJoules3.99x10^6 calories3.99x10^3 Calories
-4 degrees Celsius = 24.8 degrees Fahrenheit.Use this formula to convert degrees Celsius/Centigrade (ºC) to degrees Fahrenheit (ºF): (ºC x 1.8) + 32 = ºF
No, water needs to be at at least 0 degrees Celsius to become ice.
Use this equation to convert degrees Celsius/Centigrade (ºC) to degrees Fahrenheit (ºF): [°F] = [°C] × 1.8 + 32
