I suppose that physics is more important.
Physics mainly although you could relate it to chemistry as an alternative energy to fossil fuels
What division of science is physics is belong?
Thermodynamics do not actually refer to chemical reactions but rather the effect chemical reactions and other interactions have on particle's.
french does not belong
organic chemistry belongs to the compound of carbon and hydrogen
physics.
Inorganic chemistry studies molecules that do not contain carbon. It focuses on understanding the properties, behavior, and reactions of non-carbon containing compounds such as salts, metals, minerals, and gases.
Physics.
Physics is a branch of science. It is difficult to define a "branch of science" precisely because there is so much overlap. Generally, physics studies matter, energy and their interactions but this involves a lot of mathematics. There are also grey areas between physics and chemistry because chemicals are matter and the bonds between atoms involve energy. Biology is probably the most remote "branch of science" from physics.
Chemistry and physical science belong to physical science because they both have an object.For example in physics, you want to know how a roller coasters stay on track so the riders will not fall.It is physical science because it used an object,aroller coaster.In chemistry you use an object,liquids.You mix acids ,baces ectcetra.
The department of nuclear physics and department of theoretical physics at Guindy campus that belong to university of Madras.
They belong to the same class of Element.
