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.
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.
Water moves across the cell membrane through the process of osmosis.
An egg will sink in fresh water. Salt water is denser than fresh water, which allows the egg to float.
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.
When a wave moves through a denser medium, its speed decreases while its frequency remains constant. The wave will also experience refraction, causing it to change direction as it enters the denser medium. Additionally, the wavelength of the wave will shorten as it moves into the denser medium.
Temperature affects the way water moves by changing its density. Cold water is denser than warm water, causing it to sink. This process can drive ocean currents as denser, colder water sinks and displaces warmer, less dense water. Temperature also affects the rate of evaporation and condensation, influencing the water cycle.
salt water is denser
The particles get further away from each other as water is heated therefore making it less dense
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.
The cold air moves under the warm air because the former is denser. So Warm air is denser.
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.
The temperature and salinity of seawater determine its density. Water gets denser as it gets saltier and reaches a maximum density at 4 °C. Salinity does affect the boiling point and freezing point of water, but not its temperature.
