It turns to ice or heavy water.
This item float on the surface of water.
it becomes less dense
When something is more dense than water, it will sink. This is because the upward buoyant force exerted by the water is not enough to overpower the gravitational force pulling the object downward.
The most dense form of water is liquid water. Ice is less dense than liquid water, which is why ice cubes float in a glass of water. Water vapor is the least dense form of water, as it is a gas and occupies more space compared to liquid water and ice.
Dense water sinks in comparison to less dense water.
Cold air is more dense than warm air
Gas is much less dense than liquid.
Water is more dense.
When something is not as dense as water, it is said to be less dense or have a lower density than water.
Anything that sinks in water is more dense than water.
more dense
When cool dense water sinks, it becomes more dense because the cooler temperature causes the water molecules to contract and become more tightly packed together. This increased density allows the water to sink below warmer, less dense water layers.
