Does water expand when getting warmer?
It depends on the temperure of the water. Water actually reaches maximum density at 4 degrees centigrade. It expands or gets less dense as it increases in temperature above that.
As water gets denser how does it moves?
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.
Why is density needed to know whether a substance will float or sink in water?
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.
Does water affect density of wood?
yes water can increase the density of water as wood has the power to absorb water and so the density of water is drastically increased
How much density does water have?
Pure water has a density of 1,000 kg/m3
As water is cooled its density increases until its reaches about what?
Type your answer here... increases
As water is cooled its density increases until it reaches about?
4 degrees Celsius, at which point it reaches its highest density. Below 4 degrees Celsius, water expands as it freezes into ice.
As water is cooled what happens to the density?
As water is cooled, its density increases until it reaches its maximum density at 4 degrees Celsius. Below 4 degrees Celsius, water begins to expand as it freezes, which is why ice is less dense than liquid water.
What is As water is cooled its until it reaches about?
Type your answer here... increases
As water is cooled its density increases until it reaches about and deg C?
4°C. At this point, water is at its maximum density. Further cooling from 4°C causes water to expand and become less dense as it freezes into ice.
The density of water is decrease or increase?
yes it decreases in the water
Does water contract or expand when it is cooled?
When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%
Does heat move in or out of water cooled below 0 degrees?
Heat moves from the water to its surroundings when water is cooled below 0 degrees Celsius. This causes the temperature of the water to decrease further until it reaches its freezing point, at which point it will freeze into ice.
Why does all the water in a lake have to be cooled to 4 degrees Celsius before water can be cooled below 4 degrees Celsius?
Water in a lake is usually cooled by the cold air above its surface rather than from the ground underneath it. As the top layer of water cools its density increases and so it sinks to the bottom, bringing other water up to the surface. This water is then cooled. This carries on until the temperature reaches 4 deg C when the density reaches a maximum. Further cooling lowers the temperature of the top layer but now its density is less than that of the water below so the top layer stays on top until it freezes (if it is cold enough). That is how you can get lakes with a frozen surface but liquid water below which can sustain aquatic life and also destroy human or other life forms that fall through the ice!
What degree Celsius does water reach maximum density?
Water reaches maximum density at 4 degrees Celsius
What are three things that affect the density of water?
Temperature, pressure, and presence of impurities are three factors that can affect the density of water. As temperature decreases, water becomes denser until it reaches its maximum density at 4°C. Higher pressure can also increase water density, while impurities can lower it by disrupting the hydrogen bonding between water molecules.
What will happen if hot water is cooled?
If hot water is cooled, its temperature will decrease until it reaches equilibrium with the surrounding environment. As the water cools, its molecules will slow down, causing the water to contract and become denser. Eventually, if cooled enough, the water may reach its freezing point and turn into ice.
