Correct AnswerYes. Wind chill is a measure of the rate of heat loss. The ground, ponds, lakes, and your car will cool at a faster rate if there is wind. An example: The air temperature is 10 degrees Fahrenheit, with a breeze. If the wind chill is five below zero, heat is being removed from water as if it were five below without wind - however the water will only cool to 10 degrees, the actual air temperature - but it will cool at a faster rate than it would in calm air. The "old" wind chill chart used by weather forecasters prior to 2001 was calculated using water as the control. The "new" one is an attempt to equate the wind-feel as it relates to human skin...use the old chart to calculate the real "heat-loss-factor" as this is more scientifically sound. How wind affects skin-feel depends upon each individual, their metabolism, tolerance, exertion level... so use the original chart, the new one is junk.No! The freezing point of pure water is, as you know, 32°F. If the air temperature is not at or below freezing there is no way that any matter in contact with the air can fall below freezing. This is the first law of thermodynamics, and applies to all objects, liquid, solid or even a gas that is contained in a way so as not to mix with the air. Water placed outside at 38° degrees cannot get colder than 38° no matter what the wind is doing. In fact, even if the wind is howling and the water is already frozen as ice when you put it outside, if the temperature is 38° degrees the ice will melt and warm to 38° in time. Try this as an experiment.
There is lower preasure over water, which means that the higher pressure from the land rushes in to fill the space of low preassure, and seeing as the sea is completely flat there is nothing the shelter the wind so the wind can keep on blowing
No, it makes it feel colder.
Answer:
Wind chill is a measure of the cooling effect of wind not the temperature of the air. Wind increases the rate at which a body loses heat by keeping the air close to the warm object cooler. In quiet conditions warm air tends to stick closer to the warm object and insulates it. So the air on a windy day feels cooler than the temperature indicated by a thermometer by increasing the rate of heat loss to that of air at the windchill temperature.
The equation for this heat loss can be calculated with various combinations of wind speed and air temperature and then converted to a wind chill equivalent temperature (or wind chill factor).The equation is:
Wind Chill (Fo)= 35.74 + 0.6215T - 35.75(V0.16) + 0.4275T(V0.16)
Where:
T = Measured Air Temperature (F)
V = Wind Speed (mph)
Yes it will cool the object quicker provided there is a temperature difference between the object and the wind.
This is because the molecules of gas (the wind) will have a longer residence time against the warm object - there will be longer for the heat to transfer by conduction to the gas.
Yes, if you think about it thermodynamically the wind would be a source of energy on the water and would provide some energy as the air molecules bumped into water molecules, slowly freezing process down (an example of this would be a flowing River in the middle of winter).
a other affect the wind would have would be removing the insulating air at the surface of the water. This is the reason why wind chill is so devastating to exposed skin, and why it is necessary cover your body with wind resistant insulating materials to stay warm.
As the water freezes at the surface and forms a layer of ice both of these affects of wind chill would have little consequence the speed of water freezing below the surface. The freezing or the rest of the water would be controlled by amount of insulating ice above the water. ( water/ice has a very high specific heat capacity and is an excellent insulator) This the reason why lakes do not freeze in the winter time and why people can do things ice fishing.
In summary it would have some effect but I believe this would be minimal!
can the temperature of water effect the wind speed on the surface of the water can the temperature of water effect the wind speed on the surface of the water
No, salt makes ice melt due to ionic reactions whereas wind makes ice "melt" due to erosion. Ice is not melted by wind it is worn away.

A temp of 273 k is the temp at which water?
water can't actually reach that temperature because temperature is actually a measurement of how fast the particles in an object are moving. once they reach boiling point (100) the water particles cant go any faster and so they evaporate and change into a gas. if you left the water on the heat then it would eventually all evaporate and there would be nothing left in the container. if you put a lid on the container it would explode because the particle's would have no where to escape.
Does salt affect how fast ice melt in a cup of water?
Salt affects how fast ice melts in a cup of water. When you add salt, the melting process will be faster but it will only affect the part of the ice cube that comes into contact with salt.
How fast would water freeze at -128 F?
It depends on how much water you have.
We can find out what state water is in by how fast these move. What are these?
Particles
Why do you run slow in water?
When you are out in the woods & come across a creek you need to cross, the deep water runs slow & the fast moving water is shallow, so you should cross at the fast moving water.
Does salt affect how fast or slow water freezes?
yes it does it does not freeze as fast
Does the thickness of a container affect how fast water freezes?
No not really
Does food coloring affect how fast water freezes?
well when i observed i just did this as a science project i observed that the food coloring does affect the way water freezes i observed the food coloring freezes faster than the sink water. so the answer is yes it does affect the way water freezes.
Does salt and sugar affect how fast water freezes?
Beacuse itss
Does amount of water affect how fast it freezes?
Yes, the amount of water can affect how fast it freezes. A larger volume of water will take longer to freeze compared to a smaller volume because there is more heat energy that needs to be removed to lower the temperature of the water to the freezing point.
How does the amount of sugar in homemade ice cream affect how fast it freezes?
nk
Does adding nothing to water effect how fast water freezes?
Adding nothing to the water should not affect the rate at which the water freezes. Adding substances, though, can noticeably depress the freezing point so that it will take longer to freeze than pure water under the same conditions. Salt is commonly used for this purpose. Adding nothing to water isn't expected to do anything to the rate at which it freezes.
Which water freezes faster tap water or salt water?
The fast water beacase it is more pure.
What freezes quicker water or rubbing alcohol?
Water. Although it's not really that it freezes faster but rather that it freezes at a higher temperature. How fast something freezes has to do with both its freezing point but also how much of it you have. A drop of alcohol will freeze faster than a giant container of water (assuming the temperature of the freezer is below the freezing point of alcohol).
Does temperature affect how fast water evaporates?
Yes.
How bubbles affect how fast does water freezes?
Bubbles in water can act as nuclei for ice crystals to form, which can speed up the freezing process by providing a surface for ice to start forming. The presence of bubbles can also affect the thermal properties of water, potentially influencing the rate at which heat is transferred and therefore impacting the freezing time.
What effects how fast somthing freezes?
How cold it is.
