Generally, when a substance is warmed up, it also expands a little. But as you're not adding any more stuff to it, the density has to go down as the volume goes up. So as long as some of the water is warmer than the water around it, that water will try to rise to the top.

Can a egg float in cold water?

Yes
Why is it easier to float in cold water?
because hot water evaperates
What would be a good question for egg flotation?
will the egg float with hot water or with hot water with salt?
If cold water is denser than hot water then how can you float in a warm water?
The difference in water density (hot-cold) is very small, compared to the difference in density between water of any temperature, and your body. That is, even hot water is more dense that we are, so we still float.
can hot water float on cold?
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.
What egg will float faster an egg with cold water or an egg with hot water?
Cold water.
What floats more between cold water and hot water?
The density of cold water is greater than hot water so there will be more substances that will float in it.
What is the Difference between adding flour to cold water and hot water to flour?
Flour to cold water will just float on top, hot water to flour will cook the flour.
Does plastic float on hot water?
This really depends on how dense the plastic is. If it is denser than water, plastic will sink at the bottom. The temperature of the water does not affect whether or not something will float on that liquid.
Do things float in alcohol?
Yes. For every fluid, there are things that float in it ... they just have to be things that are less dense than the fluid. That's how stones float in mercury, logs float in water, and hot balloons float in air.
Do you have to use hot water and salt to make an egg float?
no you do not. But you can. A drop of vinegar helps!
