Why don't fish freeze in lakes during winter?
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.
Lake Pend Oreille will freeze along the shallow shores in winter. However, the lakes depth and size prevent the surface from freezing over completely.
They have feathers to keep them warm and their nests aresurprisingly warm some birds even migrate to warmer countries forthe winter
Yes, whenever something changes from liquid, solid or gas, It is considered a change in state.
During the Winter, squirrels hibernate. By hibernating, the squirrels lower their heart rate and are immune to the cold. Before hibernation, they stock up on food for the Wint…er.
To answer this question, you have to account for many variables. Excluding morphology of the lake and generalizing behavior (as well as species of fish) it is possible for fis…h to die during a freeze. Still, there are many mechanisms that allow for fish to survive these common events. Most fish adjust behaviors, by vertically migrating to allow for the change in temperature or they may migrate from the lake. Other species produce anti-freeze proteins which alter the physiology of the fish. If you need a more in-depth answer, just message me.
Most lakes actually do. Larger lakes generally will not freeze over because of movement. The water doesn't quite get cold enough to actually freeze. It's the same principle… behind why the ocean doesn't freeze. It only does at and around the poles.
Ionic bonds in water, formed when the molecule gains another electron with the presence of a second Hydrogen atom, releases exothermic heat. This stops the lake from freezing …completely solid, as water molecules tend to compact as you go deeper into a body of water.
Lakes never freeze to the bottom, so fish just live in the water below the ice.
Rivers don't freeze in the winter because the water keeps moving and doesn't freeze.
the whole water doesn't freeze (if it's not one of the poles) and fish can survive under that ice in the water because they are immune to really low temperatures.
lakes are smaller and oceans are huge.
Antarctica is a continent. In Antarctic waters, which are liquid, the fish survive there because it's their natural habitat. When the sea ice freezes, the fish simply migrat…e so that they remain in liquid.
The entire surface of a lake may certainly become frozen during the wintertime in some areas, but unless the lake in question is fairly small, it is unlikely for a lake to fre…eze completely beneath the surface. The sheer volume of water in a larger, deeper lake would make it very difficult, if not impossible.
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.
because the ice on top of the water has little atoms stick to each other and sir gets grapes in side between the atoms which makes ice flot on top of the water and that preven…ts the water from freezing and also the water below is moving in rivers and oceans
