Physical chemistry

Physical chemistry is a branch of chemistry that studies how physical forces affect chemical reactions. It focuses on understanding how changes in temperature, pressure, and other factors can affect the way molecules interact and behave. Physical chemistry looks at many different areas, such as thermodynamics (the study of energy in chemical reactions), kinetics (the study of how quickly chemical reactions happen), and quantum mechanics (the study of how particles at a very small level can influence reactions). It's like chemistry but with a focus on how physical forces, such as heat and light, can cause things to change.
