Density of Water and Thermal Expansion | Science Experiment

What is the density of water and why does ice float on water? The density of liquid water varies with temperature. Differences in temperature will cause the water to separate itself into layers. This causes a temperature gradient within a container. Thermal expansion causes substances to increase in volume as they heat up. When volume increases, density decreases for a fixed mass.
Ice floats on water because when it freezes its density decreases. Expansion on a phase transition to a solid is an unusual phenomenon. Water increases in volume. This lowers its density and causes it to float. This is why ice floats in water.
The density of a substance is based on the mass and volume of a substance. As the temperature of a substance changes, this will change the volume of the substance, which in turns changes the density.
The thermal expansion of water creates a gradient that supports aquatic life. This is why a swimming pool feels colder as it gets deeper.

This is such a fun demonstration, I wish I’d gotten to do it in school! You’re great at explaining things.

I thought everyone did this one. Tipping the jar over is much harder than it looks...hot water everywhere.

[@cardinal5000]

Great demonstration! Makes science more interesting and fun.

Sir just i want to understand what if your water is 0.5 grams and millileter then you get the density of 1g/ml so is the density for all the liquid or is it for each milliliter of this liquid that doesn't make sense at all the density would not have a unit to it.

[@TheBoringVoice]

Density is - mass in a volume. Hence the units mass and volume.

[@koma7252]

shouldn't the graph at 0'C be at 0.9 or whatever? as the ice water is less dense than 4'C liquid?

[@TheBoringVoice]

The chart here plots water in its liquid state. Liquid water at 0'C has almost the same density of liquid water as at its maximum density. When the state changes to a solid, then the density will decrease to 0.91 g/ml.

A cube with two sides 2mlong has a mass of 960kg what is its density
