What happens to water when it is heated and cooled?
Water is heated we get boiling solution (water is evaporated).
Water is cooled we get ice form(water is freezing).
Metal that is heated will expand(meaning to become larger), and metal contracts(shrinks) when it is cooled. I think that it is because when it is heated, the molecules spread apart(sort of like when you heat water), and the opposite happens when it is cooled.
they tend to vibrate
Regardless if it is water or anything else. When something is heated molecules speed up. When something is cooled molecules slow down.
If the water is heated, the germs and harmful bacterias get killed So, this water gets pured. If the water is cooled, the dead germs get cleaned and then the water is 100% pure.
it will not attract
It changes the vibrations of the molecules.
When heated it get larger and when you freeze it the matter gets smaller with an exeption to ice
It doesn't, water turns into steam, or a gas when heated. Water turns into a solid when cooled
if they are heated then they turn to a liquid, if that are a soled well they are hard like ice
Water evaporates when it is heated. It is then cooled by the air around it causing it to recondense.
What happens to bromine gas in a sealed tube when it is cooled and later heated Answer:When bromine is cooled and then heated in a sealed container, the bromine juice starts evolving in a gaseous state. It then becomes a gas i.e. bromine gas which is red-brown in color
A solid can change Into a liquid when it is heated Example- when heated solid chocolate, the chocolate changes into a liquid. A liquid Can change into a solid when it is cooled Example - If you leave juice in the freezer , the liquid changes into a solid.
Most things (solid and liquid) will expand when heated and contract when cooled. Water liquid expands when heated and cold water (below 4oC) expands when cooled, even more when it's iced (solid).
It changes color for Purple to Blue if it was heated and if it was cooled down then it will change color from purple to pink
The flesh will bring out goose pemples
when water vapour is cooled it condenses and falls as rain
Nothing happens to the mass when its cooled (or heated). Mass is the same (law of Conservation of Mass). Volume can change, though, which affects density (since mass is constant).
When it heats up it expands and rises, when it cools, it contracts and falls.
The bonds in between the particles become weakly bonded.
it is expanded when its heated, and it shrinks when its cooled
Because they are more hollow.
When water is cooled, its volume is reduced until near 4°C. After that, if it is cooled further, its volume increases.
When metal is heated to a high temperature it starts melting and when it cools down it freezes or hardens again.
No, it expands- this is because when the particles in the water are heated they move around and cause the water to expand. When water is cooled it contracts. This is because the particles in the water and coming together. When water is cooled it usually becomes ice or expands a little. The volume of ice is 4x greater than water, therefore it actually expands, rather than contracting.
Heating lead to an increase of pressure. Cooling lead to a decrease of pressure.
ummm it will definetely expand....if the materials you"re talking about is the term for science.
move faster when heated they move slower when cooled
Ice (frozen water) and Water (below 4 oC) expand when cooling. This is exceptional! Other substances, also Water (above 4 oC) expand when heated.
The water vapor turns into liquid water.
no, Liquids expand when cooled and contract when heated. Think of water freezing, the ice tends to bulge outward.
the answer said it when seam is cooled and chages to a liqid its water and when it trns into a solid its ice
water when it is heated turns into gas and gas when it is cooled turns into liquid.hope i helped
Paraffin wax melts into a liquid state when heated, but hardens again when cooled.
They shrink in size. If you carefully control how you cool heated materials, you can make precise bends in them.
Heated air will rise, cooled air will sink.
The two metals have different expansion rates when the strip is heated. This means that one of the metals will expand more than the other, causing the strip to bend.
when air(gas) is cooled(thermal energy is removed) its molecules slow down and it becomes a liquid(condensation) when air(gas) is heated(thermal energy is added) its molecules speed up, but it wont change into a different phase until gas is heated to a temperature above 10,000 C, which removes electrons from the atoms
The temperature of the water is actively regulated to maintain a fixed point. Thus it is both heated and cooled depending on what is needed to maintain that temperature.
they expand when heated and contract when cooled
It becomes a liquid.
it becomes more dence
No; water (as gas) must be cooled to become a liquid - this change is called condensation..
water is removed
(After it has been heated.) It will harden. (At room temperature.) It will become brittle. (After it has been cooled .) It will become very brittle.
the particles start to move faster and have more kinetic energy and when it is cooled it moves slower with less energy
Yes, hot water or boiling water will kill or damage plant tissue and could result in death, even if this is applied to the soil. Once the boiled (or heated) water has cooled it can be used to water the plants with no side effects
when water gets heated it starts to get excited and it stats to boil and there are atoms inside which viabrate and makes the water boil.
water does not shrink at lower temps when it freezes it changes to solid and expands, when heated it expands until the temp. changes it to a gas also known as steam water is the only element that expands when heated or cooled
