chemistry was first studdy'd 3000 years ago. one of the first well known chemists was named democratos
energy, foods and whatever!!!

Chemists specialized in this branch of chemistry.
contribution of chemistry to physics

Any contribution of anatomy to chemistry.
the contribution of chemistry in oceonology is the materials that they used
If this is a homework question, your teacher should be ashamed. The answer is probably supposed to be "analytical chemistry." However, organic chemists, inorganic chemists, physical chemists and biochemists all might do this to some extent, so really a better answer would just be "chemistry" and even that might be too narrow.
it is the contribution of human being.
First chemistry; after physics and mathematics.
Major areas of chemistry are organic chemistry, inorganic chemistry, biochemistry, radiochemistry, geochemistry, clinical chemistry, analytical chemistry, photochemistry, hydrochemistry, etc.
The most important contribution of Roy J. Plunkett in chemistry was the discovery of polytetrafluor ethylene.
Physical chemistry is a branch of chemistry in which physics has a special contribution.
This is a specialist in analytical chemistry.
