Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
What is the difference between chemical change and physical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What is the difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
Is liquid tree resin hardening into amber physical or chemical change?
Physical... chemically, it's still the same substance,
Is a broken balloon a physical or chemical change?
Physical, because the balloon did not have a change in its chemical composition when it broke.
Is breaking a balloon a physical or chemical change?
physical change
Is a balloon popping a physical or chemical?
physical change
Is a balloon breaking a physical or chemical change?
A balloon breaking is a physical change because the bonds between the molecules of the balloon are simply being broken, changing its physical form, but not changing the chemical makeup of the materials involved.
When a balloon expands as it becomes warmer is it a chemical or physical change?
physical
Is blowing up a balloon a physical or chemical change and why?
Blowing up a balloon is a physical change because the air being blown into the balloon does not alter the chemical composition of the balloon material. The change is reversible, as the balloon can be deflated and reinflated multiple times without changing its chemical makeup.
Is heating the air in a balloon a chemical change or a physical change?
Heating the air in a balloon is a physical change because it does not involve any chemical reactions. The heat causes the air molecules to move faster, increasing their kinetic energy and causing the balloon to expand.
Is a bursting balloon a physical change?
no, bursting of balloons is a physical change as the only change that occurs that that the shape of the balloon changes . Coming out of air is not a chemical change.
Is filling a balloon with hot air a chemical or physical change?
Filling a balloon with hot air is a physical change because the hot air is simply expanding and occupying more space within the balloon, without any change in its chemical composition.
Is burning a balloon a physical or chemical change?
When thinking of a balloon, it's best to think of two different chemical compounds that do not mix, the balloon itself and air. What makes the balloon pop is that the pressure of the air exceeds the force of the chemical bonds of the balloon. In order for a chemical reaction to take place, you need to start off with one set of chemicals that become a new set of chemicals.However, when a balloon pops, no new chemicals are created. All that happens is that the electron bonds of the compound we know of as the balloon break.

Why is popping a balloon an example of a physical change?
Popping a balloon is a physical change because the balloon retains its original chemical composition even after it has been popped. The change is reversible, as the pieces of the popped balloon can be put back together and reinflated.
