Finally, A Level Chemistry has allowed me to develop my knowledge of organic, inorganic and physical chemistry, and to understand how different branches of the subject relate to one another. Some chemistry teachers like to define a chemical process as any process that involves a chemical reaction and all other processes as physical processes. When a reaction creates heat, it is called exothermic, and when the reaction absorbs heat, it is endothermic. The energy used to cause these transitions can be a flame, a beam of electrons, or electromagnetic radiation (light). What type of chemist would study the energies and heats involved in chemical reactions?
