Is water is heated and changed to steam is it a physical or chemical change?
The changing of water to steam is a physical change because it is still water, but only in a different state. The steam can change back into water which is a reversible change. Chemicals changes cannot change back. They are permanent.
Is mixing water with clay a chemical change?
No, it is a physical change because the chemical composition of the water or mud does not change.
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
No. In a physical change, the substance maintains its chemical composition.
When Salt dissolving water physical change or chemical change?
It is a physical change because the chemical composition of salt and water do not change. You can separate the salt and water physically by allowing the water to evaporate, which leaves the salt.
Is freezing of water evaporation of gasoline and rusting a nail a physical change?
freezing water and evaporation is physical-only change in state of matter. rusting nail is chemical-alters composition of substance
Is boliling water a chemical or physical change?
Boiling water is a physical change because it does not change the chemical composition of the water.
Is the soulibility of water a physical or chemical nature of water?
Solubility is a physical property of water because when water dissolves a substance, the chemical composition of the water does not change.
Why is water evaporating is a physical change?
During evaporation the chemical composition of water is not changed.
Is water into ice is physical change?
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 a cube of surgar dissolving in water a physical or chemical change?
This is a physical change the chemical composition of the sugar does not change
Is being composed of hydrogen and oxygen a physical property of water?
Yes, being composed of hydrogen and oxygen is a physical property of water. Physical properties refer to characteristics that can be observed or measured without changing the composition or identity of a substance, and the specific arrangement of hydrogen and oxygen atoms in water molecules is a defining physical property of water.
Is possolving table salt in a glass of water a physical change of a chemical change?
It is a physical change because the chemical composition of the salt and water does not change.
Is freeze drying physical change or chemical?
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
Is steam turning to water a chemical or physical change?
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.
Is water is heated and changed to steam is it a physical or chemical change?
The changing of water to steam is a physical change because it is still water, but only in a different state. The steam can change back into water which is a reversible change. Chemicals changes cannot change back. They are permanent.
Is water heated and changed to steam a physical or chemical change or both?
physical only, you are only changing its state, not its composition.
Is dissolving soup in a water a chemical or a physical change?
A physical change - since the chemical composition of the soup remains unchanged.
