Water molecules are more spread out and have higher kinetic energy when they are hot, causing them to occupy a larger volume and hence be less dense. When the water cools down, the molecules lose kinetic energy, move closer together, and occupy a smaller volume, resulting in higher density.

What is Electra's real name on Tracy beaker?
Elektra's real name is Jessica Revell but she gets known as Jess :)
Where did the beaker get its name?
The beaker gets its name from its resemblance to a cylindrical drinking cup or drinking vessel. Its name is derived from the Old English word "becere" which means "drinking vessel."
If you mix and stir 2 chemical solids and the beaker gets hot what is happening to the beaker?
Depends on how fast you are stirring..... Friction from very vigorous stirring could be one answer, but while this is a real phenomemon, it is unlikely ot be significant in most cases. Another answer is that an exothermic chemical reaction is taking place between the two chemicals in the beaker.
When ice melts does its volume increase or decrease?
Water is more dense than ice. That's why ice floats in water. As the ice melts, the water level rises, but it never gets as high as the highest peak of the floating ice was.
Why does water expands at 4 degree celsius?
Water expands at 4 degrees Celsius because this is the temperature at which it reaches its maximum density. As water cools below 4 degrees Celsius, it begins to expand and become less dense, eventually transforming into ice. This unique property of water is due to the hydrogen bonding between water molecules.
What happens to ocean water as it becomes denser?
The water gets cooler
When water gets denser how does it move?
I think it sinks toward the ocean floor.
Why and how does the water inside the chilled water pipes got cooled?
The heat gets removed from the H2O
Is drinking hot water reduce the fat from the body?
No. By the time it gets to your stomach it's cooled off.
Does an under water volcano heat up the water?
if you are right above it properly yes but if you at the surface of the water it would have cooled down by the time it gets to you
When water is heated why it gets less denser?
The particles get further away from each other as water is heated therefore making it less dense
How does temperature affect 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.
What changes do you think when water heated and cooled?
When water is heated, the molecules gain energy and move more quickly, causing the water to expand and eventually turn into steam. When water is cooled, the molecules lose energy and move more slowly, causing the water to contract and eventually freeze into ice.
How bike engine gets cooled?
race bikes are cooled by air air circulation but in sports bike they are cooled by oil coolant
When air is gets cold?
when air is cooled it sucks
What is the unusual behaviour of water when cooled below 4ºC?
Most matter contracts as it gets colder. Water is one of the few substance that expands (from 4 degrees Centigrade to 0).
Why does water get cooled in a earthen pitcher?
This Cooling effect is based on the principle of Evaporative Cooling or simply cooling thru evaporation.....An earthen pitcher has pores through wich water propagates or oozes out and evaporates...the heat required for evaporation is taken up by the liquid itself...hence the heat pays off and the water gets cooled.
