Contracts.
Gas? Nearly there. Its actually called water vapour. In industrial situations it would be called steam.
decreases, as warm air can hold more water vapor than cooler air. This causes the water vapor present in the air to be a lower percentage of the total amount the air could hold at that temperature, resulting in lower relative humidity.
At room temperature (around 25 degrees Celsius), the element that will condense when cooled from 100 degrees Celsius is water. Water vapor at 100 degrees Celsius will condense into liquid water when cooled to room temperature due to the lower temperature causing the vapor to lose energy and convert back to its liquid state.
super cooled, D
The density of water at 100 degrees Celsius is about 0.9584 grams per cubic centimeter. At this temperature, water is in its liquid state and expands slightly compared to when it is at its maximum density at 4 degrees Celsius.
Sort of. In the temperature range of 0-4 Degrees Celsius water contracts when heated and expands when cooled. Outside of this temperature range it behaves normally.
contracts. This unusual property is due to water's hydrogen bonding structure, which causes it to reach maximum density at 4 degrees Celsius. As it cools below this temperature, water molecules form a more ordered structure, leading to contraction.
Yes, water contracts when cooled from 4 degrees Celsius because it is in its densest state at that temperature. As it cools further, it expands until it reaches its freezing point, at which point it expands again and turns into ice.
Water has three states Solid (ice) liquid (water) gas (steam) When water is heated it expands and when it is cooled it contracts until about 4 degrees Celsius when it begins to expand again. So the answer to your question is it depends on what temperature the water is. If it is a liquid and over 4 degrees then it will expand. If it is not frozen but somewhere between 0 and 4 degrees it will contract until about 4 degrees and then expand. Under 0 degrees it is ice not water, over 100 degrees it is steam not water.
what changes take place when water is heated or cooled
Yes, water expands when cooled below 4 degrees Celsius due to the formation of hydrogen bonds in its molecular structure. This expansion causes water to become less dense and eventually freeze into ice at 0 degrees Celsius.
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%
what changes take place when water is heated or cooled
Almost everything expands when heated. There are a very few substances that contract when heated under certain conditions... water, for example, contracts very slightly when it is headed from 0 degrees to 4 degrees Celsius.
All liquids expand when heated. e.g. Mercury in a thermometer. One exception may be water when heated form 0 to 4 degrees Celsius.
Yes, most liquids expand when heated because the heat causes the molecules within the liquid to move faster and spread out, increasing the overall volume. However, there are exceptions such as water, which expands when heated until it reaches a temperature of 4 degrees Celsius, at which point it begins to contract.
water expands on heating and contracts on cooling because when water is heated the molecules are closely packed and they overflow but when cooled they are loosely packed therefore they dont overflow. it is as simple as that.
