There is no difference on how well a toy boat will float in water depending upon the temperature. The ability for an object to float is if it can displace more than its own weight in water, which doesn't depend on the temperature of the 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.
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
Cold water.
Frick you
Only an altered egg float.
Yes
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.
They can float in hot. Like if you boil eggs, before you set the pot, water, and eggs on the stove, you see that they don't float until the water gets warm.
because hot water evaperates
It is easier to float in cold
hot
