Changes of state are physical changes.
Physical, there's no change to the water molecules involved.
Physical
actually, matter deosn't shrink, it just changes form. but its physical.
Water turning to snow is a physical change. Snow is just water that's frozen.
It would be a Physical Change.
Freezing is a physical change.
A physical change.
This is a physical change, because the rainfall will eventually change back into water vapor. It is still has the same chemical makeup.
No. It is a physical change.
Physical change, seeing as how none of the chemical makeup of the water is changed.
The physical properties of water will change when it freezes, turning from a liquid to a solid
well ! actually it is a very simple phenomenon.....because of the icy cold water, the air around it gets condensed when it comes close enough. consequently, the condensation causes the water vapors in the air to change into droplets that then appear on the surface of the container of that icy cold water...
Assuming you mean liquid water turning into gaseous water, that is a physical change, because it's still water (H2O.)
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.
Physical change, because the water is only changing state, from a gas to a liquid.
No. That is a physical change of the liquid water turning to gas (steam)
A physical change is something that does not change the chemical makeup of a substance. For example, water turning into vapor is a physical change because the composition is not changed. Water vapor still has hydrogen and oxygen just like water.
Physical
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
Melting is a physical change.
No, freezing is not a chemical change. It is a physical one. It (freezing) is reversable, and the substance that is changing state to a solid or from a solid is not undergoing any chemical changes.
Boiling water is a physical change because it does not change the chemical composition of the water.
No, freezing water is not a chemical reaction. It is a physical change which water undergoes at temperatures below 0oC. At higher temperature the ice melts back to water again.
is water and oil a physical change or chemical change.
