How is the water water seer physics?
Yes it physical change.physical change is a change that expressed as no new substance with new composition is formed.when water is changed in to ice there is no new substance with new composition formed.the only change is only water particles are compacted to form the solid ice.
Is there more of an iceberg under or over the water?
In water, most of any piece of floating ice is under the surface,and only a small amount of it is above the surface.
Why does it take longer for a full kettle of water to boil than a half full kettle?
The more water in the kettle, the longer it will take to reach boiling point. This is why it is wasteful in energy to boil a full kettle if you only want to brew a small cup of tea.
Can both liquid water and steam exist at 100 degrees Celsius?
Liquid water can exist at (and above) 100 degrees Celsius if the pressure is increased above one atmosphere (about 100 000 Pascals). The high pressure squeezes the molecules together, and does not allow them to separate into a gas. This forces it to remain as a liquid, despite the high temperature. Of course, water vapour (steam) can certainly exist above 100 degrees Celsius.If you're interested in how the two phases exist together, if you heat water to 374 degrees Celsius and increase the pressure to 218 atmospheres, the properties of the liquid and the vapour merge together to form only one "supercritical fluid" phase.
When energy changes forms energy is always produced?
No, energy is not produced. The total amount of energy doesn't change.
What happensin airconditioningwhen humiditylevel is high inatmosphere?
the humidity condences and you get pure water. the air can only hold a certain amount of water vapour, that amount rises with temp so when you cool the air you can have excess water vapour which will condence to liquid water.
Why is the water cycle a physical change?
because during a water cycle only the state of the water molecules are changed i.e. first from liquid to vapour and then to solid (snow and hailstorm) or liquid (rain). since there is a change only in the physical state of water and there is no change in the chemical properties of the water molecule it is a physical change.
What is the Difference between airs and gases and water vapour?
Air is the mixture of different gases (like oxigen, nitrogen, co2 e.t.c.) & water vapour. Gases are only gases, here is no water vapour. And water vapour is form after the vapourization of water at high temperature.
What is found in water vapor?
Water vapour is only made of evaporated water
Are plants the only living thing that gives out water vapour?
No! The stuff that comes out of your mouth, for example, is water vapour. The foggy stuffs!
Do people only exhale CO2 and water vapour?
no
Water vapour in the atmosphere is confined only to?
ionosphere
Which processes is responsible for changing liquid water into water vapour?
The change of phase from liquid to gas is called vaporization (when the phenomenon is in all the mass) or evaporation (when the phenomenon is only at the surface).
What is the only waste product from fuel cells?
water vapour
Is water vapour is present in air only during the monsoon?
no
How do you trap water vapour?
Well the material to make alveolus traps water vapour while only letting oxygen and carbon dioxide through
Water cycle effect water amount?
No it does not affect the amount of water, but only change the position
