What changes do you think when water heated and cooled?
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.
Do any matter expand when cooled and contract when heated?
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.
How does an air cooled chiller work?
The air cooling of a chiller signifies , the cooling of radiator. in a chiller the compressor compressors the gas which on expansion cools in side Copper tubes causing the chilling effect. The refrigerants get heated up when compressed in a compressor. this heated refrigerant is cooled by blowing air in air cooled chillers. There are also water cooled chillers.
On the basis of hydrogen bond explain the anomalous behaviour of water when it freezes?
Anomalous expansion of water takes place because when water is heated to 277K hydrogen bonds are formed. Though ice is supposed to expand when it is converted into water, this gradual formation of hydrogen bonds causes it to contract, i.e. the contraction caused due to the formation of hydrogen bonds is greater than the actual expansion of ice. At 277K water has the maximum density because all the hydrogen bonds are formed by 277K beyond which water obeys the kinetic theory of molecules, an increase in volume when heated and the reverse when cooled. The same thing happens in the reverse when water is cooled beyond 277K. I think this should be the answer of this question
Why does iron rims are heated red hot before 'fixing' them on cart wheels?
The rims expand slightly when heated. Once they're in place on the wooden wheel frame, they're cooled with water - making them shrink tightly to the circumference.

Why does water change into a solid when it is heated?
It doesn't, water turns into steam, or a gas when heated. Water turns into a solid when cooled
What phiscal change does water go throgh when it heated or cooled?

Why do rocks get heated and cooled faster than water?
Because they are more hollow.
When water a 4 degrees C is heated it expands When water at 4 degrees C is cooled it?
Contracts.
When water at 4 degrees c is heated it expands When water at 4 degrees c is cooled it?

How does water changefrom one state to another?
Water changes from one state to another by being heated or cooled

Does Water have to be heated in order to move from a gaseous to a liquid state.?
No; water (as gas) must be cooled to become a liquid - this change is called condensation..
