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.
Is water at room temperature a physical property?
Yes it is. Properties like Boiling and melting points are physical properties.
Do the physical properties of water change when a compound is dissolved in water. If so which properties change and why?
The physical properties of water can change when a compound is dissolved in water. The dissolved compound will determine which properties change. Some will change the surface tension, others will change the pH. Many changes are possible.
Is separation of water and gasoline a physical change?
No, it is a physical change. The water and gasoline retain their chemical and physical properties.
Physical and chemical properties of chloroform water IP?
Uses of chloroform water
Is rain evaporation physical or chemical?
Physical change from liquid to vapour. The water remains chemically the same whether liquid or vapour.

When do water undergo a change in physical properties?
These physical properties depends on the water temperature.
When a matter undergoes a physical change has its physical properties changed?
volume, shape, ability to reshape itself, how it feels ( wet, hard, soft etc. ), its temperature, colour perhaps [ blue water or ice can become transparent water vapour ].
What is the change in the physical state of both lavender oil vapour and water vapour as they cool?
they turn from gas to liquid
Why is condensation of water vapor is a chemical change?
It's not !... It's a physical change. Chemically - whether water is frozen into ice, is liquid as water or a vapour (steam) - it's still the same substance.
Is the conversion of liquid water into gaseous water is a chemical change?
No, the only thing being changed are the physical properties of the water, its still just water after the conversion
Why is paper's physical properties different from water's physical properties?
There are a lot of reasons why paper's physical properties differ from water's physical properties.Paper is a solid, water is a liquid.Water is transparent, paper is not.Water flows smoothly, paper does not.etc.
What are the physical properties of water cycle?
water
Is steam a chemical raection?
NO!!!! It is a physical change of water from liquid to gas(vapour).
Why is boiling of water considered a phyiscal change?
Because physical state of water is changed from liquid to vapour.
What is change in the physical state of both lavender oil vapour and water vapour as they cool?
they turn from gas to liquid
