A scientist would probably be a physicist or a chemist, but engineers can also study energy, and designing heat engines would be an engineers job. A specialist in this field would be a thermodynamicist.
A physicist would study motion, force, and energy. Physics is the branch of science that deals with the study of matter, energy, motion, and force.
One type of atom (element or isotope) is converted to another. This is called nuclear reaction.
The nucleus of an atom can store potential energy, which is released when nuclear reactions occur, such as fission or fusion. This energy is harnessed in nuclear power plants or in nuclear weapons.
The bonds between the protons of a silver atom are classified as nuclear binding energy. This energy arises from the strong nuclear force that holds the protons together in the nucleus of the atom.
Nuclear energy is the type of energy stored in the nucleus of an atom. This energy can be released through processes such as nuclear fission and fusion, which convert small amounts of mass into large amounts of energy.
A Nuclear Physicist or Researcher or Technician would be scientists who know that.
A mineralogist studies minerals.
An ecologist studies pollution
Nuclear energy, which is a kind of potential energy.
The kind of scientist who studies Urology would be a Biologist, since Urology concerns a biological function (urination). If you mean the kind of doctor who studies Urology, that would be a Urologist.
meteoroligists
Audiologist
An Ichthyologist.
Botanist
cosmologists
seismologist
a biologist
