For Strawberries, they have found if they water them in and let the ice cover the plant, it protects the fruit by not letting it get any colder than freezing at 32°.
That would be ice.
Why should the water pipes in houses be well insulated so that they are not likely to freeze in winter?
if the water in the pipes freezes, it will expand and break the pipes.
It can, but usually doesn't for two reasons : it is not exposed directly to the air, and there is generally water being added which must also be cooled to freeze. Water in mot…ion can more easily distribute heat energy, so a large amount of the water would have to be continuously cooled to turn it all to ice.
How can winter white frost can form on the ground when minimum temperature indicates well above freezing?
It can't if it is "well" above freezing, but certainly if it is only a few degrees. The surface on a calm, cold night will radiate heat away from it rapidly. If there is littl…e wind to mix the air, the coldest air near the surface will sink to the ground so that the temperature right at the surface where frost forms is at or just below the freezing point, while just above that where temperature is officially measured (2 meters) it can be several degrees warmer.
Regardless of how your hands react to frost bite here is the procedure to winterising your pool You will need Acid/Alkali Shock Chlorine gran…ules Long Life Winterise Liquid Chlorine Make sure the pool is clean The pH should be brought to 7.4 to 7.6 use Acid or Alkali as needed Super chlorinate the water to 10ppm. Add a long life Algaecide. Follow the directions on the bottle re dosing. Run the pump for about 8 hours to mix the water and chemicals thoroughly Check the pool, once in a while during winter and ensure the pH is between 7.4 and 7.6 . The chlorine level is above 5 parts per million. If you need to add chlorine distribute it as evenly as possible throughout the pool and stir it up, concentration of chlorine can cause liner bleaching. As the temp starts to increase after the new year keep a particular eye open for algal blooms Thoroughly clean or backwash the filter; Lower the water level to below the skimmer weir; unless the pool is in a high water table areas, where a partially empty pool could start to float in ground water. In that case seek advice from a local pool expert. Remove skimmer weir and basket and store out of the weather. Partially fill a plastic bottle with anti freeze mixture or small stones or sand and place in skimmer barrel to prevent ice damaging the skimmer. Add winterising chemicals and allow circulation the filter, pump and heater must be drained for the winter and there most be no exposed holding water. Spray the electric motor and any electrical equipment with a moisture repellent spray or even better remove the pump and store it in warm dry conditions. Switch off electrical equipment. If a heat pump is fitted flush it with clean water. If an auto chemical feeder is fitted, remove the chemicals and flush it also with clean water and drain it. Under particularly harsh conditions where the water may freeze: tie a row of half filled plastic containers partially filled with anti-freeze solution or sand along the centre of the pool. This forms a break in the ice and relieves pressure the sides. don't break formed ice as sharp edges may damage the pool lining.
Rime frost is freezing water vapor that condenses at ground level.
They swim about slowly in a circle (sometimes with other aquatic birds) as a group which prevents (up to certain temperatures) the water around them from freezing. ----------…-- The blood flows throughout the body and helps maintain a steady temperature. So the ducks don't freeze to death or shrivel up and die.
In any given area temperature below ground surface changes to a subtle degree, but that does not affect water's temperature. Actually, it's the air in the atmosphere that tend…s to change its temperature both in summer and winter. So, in summer, your hands are warm already and when you touch the groundwater, you find it cold. But in winter (esp, chilly ones) your hands are cold and you find that same water warm. Generally speaking, earth gets warmer and warmer as you travel down to its core and is hottest at its core. Hope that helps. Syed Asad Hamdani.
yes depending on the temperature it might freeze completely
If you throw a glass of water into the air when it is extremely cold can it freeze before it hits the ground?
In most conditions, no. Assuming you have the glass of water sitting at the same temperature as the outside environment, if the external temperature is low enough to be be…low freezing temperature (0 Celsius/32 Fahrenheit) then the water in the glass would already be frozen before it was thrown. However, let's assume the water is in an above-freezing environment, then quickly taken into a below-freezing environment, and thrown from the glass before it can freeze inside the glass. I've seen videos of this happening, and the flying water particles do indeed freeze in mid-air, however since the water is so dispersed in the air it doesn't turn into a chunk of ice like you might expect, instead it turns into something resembling snow as it's thrown and flutters out in a cloud. From what I hear, for this to happen it needs to be somewhere around -50 Fahrenheit.

It Simply Doesn't... This Myth Is A lie
What are the special properties of water that enables fish to survive in lakes that freeze in the winter?
A2. The whole of the lake volume does not freeze in winter. Due to the fact that ice expands when it freezes, and consequently floats. My old science teacher pointed out that …this is a GOOD THING, so the fish don't get stuck! A1. Fish benefit from many properties of water; just to name a few, water's capability as an oxygen carrier enables the proper functioning of fish's respiratory and metabolic processes, and its properties as a solvent allows the precise concoction of solutes and molecules that dictates the balance of the entire ecosystem. The unique property of water that specifically enables aquatic life forms to survive drastic temperature changes, however, however, is the same property that is largely responsible for providing the suitable conditions allowing the formation of life on Earth: The high specific heat capacity of water. Specific heat capacity is a measurable physical quantity that represents the amount of heat per unit mass required to change the temperature of a substance by a degree. Therefore, the high specific heat capacity of water sets forth a large thermal energy requirement for each degree of change in temperature. Consequently, a large shift in above-surface temperature (e.g., 30 degrees Celsius) translates to a much smaller shift in the water temperature (e.g., 10 degrees Celsius). In other words, a large body of water can be thought of as a thermally stable system resistant to temperature shifts. This very special property of water is a result of the extensive hydrogen bonding between the individual water molecules. This network of intermolecular interactions that enables water to absorb a large amount of energy before undergoing change is also responsible for other unique thermodynamic properties of water such as its high boiling point.
I think you are probably talking about the fact that frozen water (ice) is less dense than liquid water, so freezing temperatures will enable the ice to form on top of the wat…erbody, but still allowing liquid water underneath so fish can survive. Also, ice is usually translucent, so it can still penetrate the ice, allowing algae to continue to photosynthesize, providing oxygen for the fish below.
To open an in ground salt water pool after the winter, you should first test the water. It will have to be adjusted to bring the alkalinity and PH to where it should be, a…s well as the chlorine, and stabilizer. Adjust the alkalinity first, and then the PH. Next take care of the chlorine, and stabilizer. Finally, add your salt to the pool.
