– Atkins shows how pressure arises from the change in momentum of molecules colliding with the walls. The equation [ P = \frac13 \fracN m \langle v^2 \rangleV ] (where (N) is number of molecules, (m) mass, (\langle v^2 \rangle) mean-square speed) appears near this point. chimica fisica atkins pdf 56
The book is massive in scope, covering everything from thermodynamics and quantum mechanics to kinetics and spectroscopy. Because the full textbook is often a heavy, hardcover volume running over 1,000 pages, students frequently search for versions of specific chapters for easier study on tablets or laptops.
