What else can I help you with?
When you boil an egg does the water the egg or the pan undergo a chemical change?
Egg goes from liquid to solid. Water becomes steam, pan becomes hot. Cooking = chemical change.
When liquid becomes a water vapor is that a chemical reaction?
no. chemical reaction requires a new substance to be created
Is the boiling of water until it becomes water vapor is a physical or chemical change?
It's a physical change. All changes of state (solid to liquid, or liquid to gas, for example) are physical changes.
When ice melts and becomes water has a chemical change taken place?
No. That's because it is still water whether it is in the form of a solid or liquid. A physical change occurs when there is a change in the state of matter only.
Why liquid water changing into steam is a physical not a chemical change?
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.

Is water changing from liquid to gas a chemical reaction?
No, water undergoing a phase change is a physical change, not a chemical change.
Is the condensation of water vapor a chemical change?
A phase change is not a chemical change since the chemical remains the same; water is still water, whether it is in the solid, liquid, or gas phase.
Why liquid water changing into steam is a physical not a chemical change?
The steam when cooled changes back to liquid water. A chemical change is usually not so reversible.
Is density a physical change or chemical?
A change in density may accompany a Physical change. When liquid water becomes solid water, the solid water FLOATS; (is less dense) on top of its liquid form.Density itself is a physical property, not a change.
Is water condensing a physical or chemical change?
Water condensing is a physical change. It is a change in state from the gaseous phase (water vapor) to the liquid phase (liquid water) without any change in the chemical composition of water molecules.
Can heating water to change it to water vapor be a chemical change?
No, this is definitely a physical change, absolutely not a chemical.
Is evaporation a chemical or physical change?
While boiling isn't the same as evaporation in that the entire liquid is heated to the point of steam and not just the surface molecules, the same physical change that causes evaporation can be seen in boiling. When boiled, a liquid becomes hot enough that it converts from that form into a gas, and if gathered and cooled, that gas reverts to its liquid form. For example, if a pot of boiling water is covered to trap the steam, that steam gathers on the inside of the cover where it again becomes water. This not the result of any chemical change in the water, just a change in its physical form.SO, EVAPORATION IS A PHYSICAL CHANGE.
Is condensation of water vapour is chemical change or a physical change?
Condensation of water vapor is a physical change because it does not involve a chemical reaction. It is the process of gas turning into liquid without any change in the chemical composition of the substance.
