Phase change is a physical change.
when fireworks go off, the energy released show a chemical reaction. gasses such as carbon dioxide and particles of smoke go up in the air.
I don't think there are any. Chemical bonds are many orders-of-magnitude weaker than nuclear bonds, so I don't think you can convert chemical energy to nuclear energy, at least, not directly.
Grinding meat is an example of a Physical Change, as opposed to a Chemical Change or Nuclear Change.
A battery is chemical energy creating electrical energy. Nuclear is cause by nuclear material either decaying or undergoing fusion, only present in nuclear material. Mechanical energy is a physical force cause by the transfer of kinetic energy.
diatomic molecules are made up of two atoms. These two atoms can either be the same of different chemical elements. Depending on what elements are in place well that depends on what kind of bonding. For example in class i learned that a homo-nuclear diatomic molecule is non-polar and covalent.
yes, it makes a covalent bond at that point
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Non-nuclear reactions can be chemical, electrical or physical - the nuclei do not change in size, electrical charge, or properties. For example, Physical: water turning into ice or steam; heat conduction; trash compaction Chemical: mixing baking soda with vinegar; Electrical: electrolysis; electroplating
No. Nuclear energy is a type of energy that is quite different from chemical energy.
Nuclear (ie per unit weight)
It is a nuclear change because there is a change in the nuclear structure of Uranium.
The radioactive decay of radium is a nuclear change. This differentiates the transformation from a chemical or physical one.
when fireworks go off, the energy released show a chemical reaction. gasses such as carbon dioxide and particles of smoke go up in the air.
nuclear changes physical '' chemical ''
Physical Change. =KDML= ;)
physical
I would say it is actually both. Fusion itself is a chemical reaction but it is powered by a physical feature named gravity.
