yes
Cold water.
Frick you
Only an altered egg float.
Yes, as hot water is less dense than cold water so it will float on top of cold water. Over time the temperatures will equalise due to natural conduction and convection.
Yes
In hot water the molecules vibrate faster than cold, resulting in the same number of molecules taking up a larger space. This means that hot water is less dense than cold water, and thus floats above the cold water.
It is easier to float in cold water because cold water is denser than warm water, providing increased buoyancy to support the body. Additionally, cold water can cause vasoconstriction, reducing blood flow to the extremities and helping to conserve heat, which can also contribute to buoyancy.
The density of cold water is greater than hot water so there will be more substances that will float in it.
Cold will sink to the bottom. Hot water will rise to the top.
a steel ball bearing will drop faster in warm water then cold water, a beach ball will float better in cold water because cold water is more dense.
Yes, fresh eggs typically sink in water, but as they age, the air cell inside the egg grows larger, causing the egg to float. This is because old and stale eggs have more air inside their shells. Temperature doesn't have a direct impact on whether an egg will float or sink, but colder water can slow down the release of air from the egg, so it may take longer for a fresh egg to float in cold water compared to room temperature water.
Yes ice will float in cold water or any water for the matter. For example icebergs are in fridge cold water (for the ocean can be extremely cold because of the salt and thus takes a colder temperature to freeze) and this still are afloat. Ice will actually float in warm or hot water for a bit until it is dissolved. So yes it can float in any sort of water despite the temperature.
