KEY POINTS:
- Physical Chemistry deals with observing the world on a macroscopic scale, with pure physics being applied to chemical problems. Matter is looked at on a molecular and atomic level, the way chemical reactions happen elucidated and the potential uses of materials considered.
- Some more particular sub divisions within this branch of chemistry include:
- Quantum Chemistry – looking at the strength and shape of bonds, and how light is absorbed or emitted by compounds.
- Spectroscopy – how electromagnetic radiation interacts with matter.
- Chemical Thermodynamics – enthalpy, entropy, and equilibrium as detailed in other parts of Heavy Metal Chemistry.
- Chemical Kinetics – delving into the speed at which reactions occur, the variables that dictate overall rate, and the mechanisms involved.
- Electrochemical Cells – building on the basics of electrolysis to look at the transfer of chemical energy to electrical energy.
- Careers that would involve a background in physical chemistry include Astrochemistry, Chemical Engineering, Computational Chemistry, Nanochemistry and Nuclear Chemistry.
THINK OUTSIDE THE BOX:
- How environmentally friendly are electric cars – considering the source of the electricity used to charge the car?
- How do geckos stick to walls?
