Why is it physical change if the steel wool turned the black pot shiny silver?
Physical change: the steel wool only changes the black pot's shape and in doing so reveals another color in the pot or the color of the substance that the pot is made from; it would still be the same thing but there would be all the parts of the pot, just it would be in different pieces.
When a can is crushed does it go through a physical change or a chemical change?
Yes, a crushed can has chemical properties. They are the same as those of the can before crushing. Crushing a can is a physical reaction and not a chemical one. For instance, if a soup can is made of steel, the steel can be chemically attacked by something like sulfuric acid. And this is true whether the can is crushed or not.
Would you get a physical or chemical change if you broke a mineral in half?
Physical change
When milk spoils it smell bad is this a physical change or chemical change?
It is a chemical change because you cannot not make the smell go away, if you could it would be a physical change
Is crushing ice is a example of physical change?
A physical change only. Its still ice. Even if it melts to water, its still a physical change.Crushing something would result in a physical change.
What would cause physical change in a bar steel?
Cutting the bar in half, melting it, heating it, grinding or filing it, drilling holes in it- and it is still steel. It has not changed chemically.

What would cause the physical change of an ice cube turning to water?
heat
Is a car crashing a physical or chemical change?
The key here is what happens to the matter. Does it change into a different material or just change shape? If the metal changes into a new substance like iron into rust then it would be chemical but this is definitely a physical change. - - - - - Car crashes can cause both physical and chemical changes. The bending of the car is a physical change, but if the wreck catches fire that's a chemical change.
Which of the following could cause a physical change in a solid piece of sodium metal?
Heating the solid piece of sodium metal can cause a physical change by melting it into a liquid. Cooling the liquid sodium back to its solid state would also be a physical change.
What could cause a physical change in a solid piece of sodium metal?
Exposure to air or moisture can cause sodium metal to oxidize and form sodium hydroxide, a different chemical compound. This chemical reaction would result in a physical change in the appearance and properties of the sodium metal.
If the temperature of heptane increased from 90 degrees to 100 degrees would a physical or chemical change take place?
The temperature increase from 90 to 100 degrees for heptane would not cause a chemical change. It would only result in a physical change, such as a phase change from liquid to gas.
Why do you use oil in your engines?
For lubrication. Steel on steel would cause friction with would lead to heat which would cause seizing of parts and destroy the engine.

Is a car wreck a chemical change or a physical change?
When a car is turned into a wreck, this involves a physical change because the molecular composition of the car doesn't change. After the crash it will still consist of steel, petrol, etc. However, if one was to set fire to the car, it would undergo a chemical change: its molecular composition would change because the molecules would bind with the oxygen molecules in the air.
Does it hurt when you transform into therian animal form?
I am going to assume you are asking about physical changes. For a physical change to take place your internal and external body structure would have to change so in theory yes it would hurt a lot. bones would need to shift and changes places which would certainly cause pinched nerves.It is important to note that a physical change is NOT something that is possible.If you were asking about mental change then there is no physical pain involved with that
If you scratch glass with a steel knife would that be a physical change because it doesn't really change the molecules?
Yes, exactly. If you ever do not know just remember that the basic chemical properties of glass and scratched glass are the same, so it's definitely a physical change. good job!
