Is a bomb exploding a physical change?
An atomic bomb uses fission-- the splitting of atoms. It is purely a physical change, at first. Any gases produced in the air surrounding the explosion (which occurs before it touches the ground), along with the intense heat produced, causes chemical changes in the air.
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
When sandpaper smooths a piece of wood what kind of change is it?
this is a physical change
Is painting wood a physical or chemical change?
Its a physical change
Is stapling an envelope a physical change or chemical?
A physical change
Is splitting a log with an axe a physical or chemical change?
Splitting a log with an axe is a physical change. The log is being physically divided into smaller pieces, but its fundamental chemical composition remains the same.
Is splitting wood chemical or physical change?
Flammability is an example of physical and chemical properties.
Is the splitting of liquid water into oxygen gas and hydrogen gas a physical change?
no, it is chemical.
Is splitting uranium in a power plant a physical nuclear or chemical change?
It is a nuclear change because there is a change in the nuclear structure of Uranium.
Is splitting water through electrolysis into O2 and H2 gasses a physical or chemical change?
In a way it is both physical and chemical, because a chemical change is changing how the molecule is "built," while a physical change is the transformation from one form to the other. I would consider splitting water through electrolysis as a chemical change at first because physical change is keeping the build of a molecule the same while it's form changes. You could also say that the splitting itself occurs first, meaning chemical change first occurs. Physical change would the occur later because the points of physical forms change based on the atom or molecule. The time difference in which occurs first would be very hard to measure, down to nanoseconds, but according to common scientific sense chemical change would occur first. The true answer to this question would be that it is chemical change, because you wanted to know what the splitting part was. Hope this helps!
Is splitting a diamond a irreversible change?
Yes, splitting a diamond is considered an irreversible change because it alters the physical structure of the diamond, making it difficult to reconstruct it to its original state without significant loss of material and value.
Is a bomb exploding a physical change?
An atomic bomb uses fission-- the splitting of atoms. It is purely a physical change, at first. Any gases produced in the air surrounding the explosion (which occurs before it touches the ground), along with the intense heat produced, causes chemical changes in the air.
