Is Boiling oil a physical change or a chemical change?
Physical ... it's only a state change. Cool it and it reverts to its old condition.
Is mixing oil and water a chemical change?
Oil floating on water is not a "change", so asking whether it's a physical change or a chemical one is nonsense. To the extent there's any meaning at all to the question, it's a phenomenon caused by the physical properties of the two materials.
Is mixing oil and water chemical or physical?
It is a physical change because the oil and the water do not change in chemical composition.
Why changes of stat are physical changes?
Changes in state are physical changes because they involve a change in the physical appearance or state of a substance without altering its chemical composition. For example, when water changes from a liquid to a solid (freezing) or a gas (vaporization), it is still water chemically. This contrasts with chemical changes, which involve a rearrangement of atoms and result in the formation of new substances.
When you heat up water and it changes to steam is it a physical or chemical change?
physical change because you are not doing anything to the object to change its ingredients or the way it is constructed and all you are really doing is adding heat.
When water changes phase is it chemical or physical?
Physical, as it remains water.

Is water turning to snow a chemical or physical change?
Changes of state are physical changes.
Is mixing oil and water a physical?
Yes
Is Mixing oil and water a physical change?
Mixing oil and water is a physical change because no new substances are formed. The molecules of oil and water remain the same, they are just physically mixed together.
When water melts from an ice cube this is an example of a physical change The water changes from a?
It changes from a solid to a liquid.
Is the freezing point of water a physical state?
No it is the temperature at which water changes physical state from a liquid to a solid.
If water is boiling is it a chemical change or a physical change?
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
Is mixing oil and water chemical or physical?
It is a physical change because the oil and the water do not change in chemical composition.
What are things that have physical changes?
Water because It is first solid its ice then when it melts it is liquid and when it is a gas its water vapor.
What is oil viscosity?
Viscocisty is the physical properties of fluids (oil in this case) to resist flow. This can better be described as thickness. It is known that this property changes when the fluid (oil) rises in temperature. Viscosity is how THICK the oil is. Thin oil flows like water, thicker oil starts to flow more like honey. Lower numbers tend to be more like water.
