Problems in Undergraduate Physics, Volume IV: Molecular Physics, Thermodynamics, Atomic and Nuclear Physics presents a set of problems in physics as well as answers and solutions in the second part. This book covers several subjects, including thermometry, atoms, kinetic theory of matter, surface tension, thermodynamics, and thermal conductivity. Organized into two parts encompassing two chapters, this volume begins with several problems involving molecular physics, particularly calorimetry, thermal expansion, and thermometry. This text proceeds with a set of problems concerning atomic and nuclear physics, including the quantum nature of light, the wave properties of particles, X-rays, and structure of the atom and spectra. Tables at the end of this book provide information on the range-energy relationships for particles in emulsions as well as well as on the uranium-radium radioactive series. This book is intended to be suitable for students in physics. Teachers and research workers will also find this book extremely useful.
