When a substance undergoes a phase change what occurs a particle change a chemical change a new substance is formed a physical change?
During a phase change, the substance transitions between different states of matter (solid, liquid, gas) without any change in the chemical composition of the particles involved. This means that there is no new substance formed and no chemical change taking place, it is solely a physical change.
Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Is a new substance is produced a chemical or a physical change?
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.
When a new substance is produced is it a physical or a chemical change?
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.
What is the reason why melting of ice is a physical change?
It's a physical change because no new substance is produced. Liquid water and ice are the same substance with particles arranged differently.
Why physical changes can easily be reversed but why chemical cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Can a substance produced during a physical change easily change back?
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
Is reacts with acid to form H2 a chemical or physical properties?
This is a chemical property, as it involves a chemical reaction where hydrogen gas is produced when the substance reacts with an acid. Physical properties refer to characteristics such as color, state, density, and boiling point.
What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
What is the diffence between a physical and chemical change?
Physical change doesn't produce a new substance, but a chemical change is a new substance.
