Water increases in density until 4 degrees Celcius, when its density starts to decrease again due to hydrogen bonding. (see Wikipedia.org for more.) As water moves away from the equator, it gives off heat. As it cools, its density increases.
Water does not change density.
it sinks to the ocean floor
yes chalk is denser then water.
no
Using water is an example, anything that is less dense than water will float on water. Anything that is denser than water will sink in water.
An egg will sink in fresh water. Salt water is denser than fresh water, which allows the egg to float.
Sound waves travel faster through denser mediums, and water is denser than air, so sound travels faster through water than air
when the water cools down it gets denser
The water gets cooler
I think it sinks toward the ocean floor.
Land gets hotter than water. So air above land gets warmer. Warm air rises. Denser air from the sea moves into area with "less" air.
By physical examining the milk and water, you can easily judge that milk is denser than water. As milk is denser, its molecules require more energy to gets excited and evaporate as compared to water.
The Coriolis Effect causes water to be pushed onto shore and when the water on the surface of the sea becomes denser than the water beneath it, it sinks.
salt water is denser
The particles get further away from each other as water is heated therefore making it less dense
The cold air moves under the warm air because the former is denser. So Warm air is denser.
Vinegar is denser than water because vinegar is made of different substances that are denser than water, so that means vinegar is a little denser than water.
Light enter the water base on the principle of refraction of wave,during this process light moves from a denser medium to a less denser medium leading to the change in wavelength of the light That, however true, is not an answer to the question. (VanZanten)
yes chalk is denser then water.
