Water freezes at 0 clecuis and 32 farenghit
It depends what temperature you try to freeze it at.
Yes. Water vapor in the air can condense (like the water that forms on your cold glass of soda) and fall. If the temperature is warm, the water falls as rain. If the temperature is cold enough, the water freezes and falls as hail or snow.
32
temperature
because water is generally cold unless heated in a kettle. Coffee on the other hand is warm when you make it so if the water is colder to start with it will take less time to freeze.
The time it takes for warm water to freeze depends on factors such as the initial temperature of the water, the volume of water, and the surrounding temperature. Generally, warm water will freeze faster than cold water due to the Mpemba effect, but it still typically takes a few hours to freeze completely in a standard freezer.
The starting temperature will certainly affect the time it takes for water to freeze. By definition, the temperature will be the same for both the water that started warm as it is for the water that started cool when they both freeze. The time difference comes from going from warm (~85 degrees) to freezing (32 degrees) and from cool (~50 degrees) to freezing (32 degrees).
cold water
You can freeze anything with water in it. Pineapple does have water, so if you drop the temperature low enough, it will freeze.
The amount of energy required to freeze water depends on the initial temperature of the water and the desired final temperature (0°C for freezing water). To calculate the power in watts needed to freeze water, you would need to know the mass of water, its initial temperature, and the time over which you want to freeze it.
yes
Yes. It is a proven fact by scientist that hot water will freeze faster than cold or warm. This process is called " The Mpemba Effect ".
if you add salt to water, it will freeze at a lower temperature.. i do not think it is possible at a temperature below zero degrees.
Yes, moving water can freeze if the temperature drops low enough.
Water pipes can freeze when the temperature drops below 32 degrees Fahrenheit (0 degrees Celsius).
No, hot water does not freeze more quickly than room temperature water. In fact, hot water takes longer to freeze because it has to cool down to the same temperature as room temperature water before it can start freezing.
Absolutely. Water must achieve a temperature below 32°F before it can freeze. The closer the water is to room temperature, the quicker it will freeze. There is a phenomenon in which warm water freezes and cold water not: In some regions(e.g. Siberia) it is possoble to pour boiling hot water to the ground and it will freeze even before it hits the bottom. This is possible as hot water's molecules are moving more heavily than those of cold water. Therefore the surface of the water is bigger and warmth can leave the molecules faster. I remember a report of a experiment at one of the university's found hot water froze faster by a inute.
