Properties, states and phases of a pure substance

Properties, states and phases of a pure substance

Properties, states and phases of a pure substance. I am teaching Engineering Thermodynamics using the textbook by Cengel and Boles. Many figures in the slides are taken from that book, and most others are found online. Similar figures can be found in many places.

Ch. 10 --Gases

Ch. 10 --Gases. Properties: Gases are highly compressible and expand to occupy the full volume of their containers. Gases always form homogeneous mixtures with other gases. Gases only occupy about 0.1 % of the volume of their containers. Measuring Gas Pressure.

Chapter 12 : Day 2

Chapter 12 : Day 2. IDEAL GAS LAW. Using KMT to Understand Gas Laws. Recall that KMT assumptions are Gases consist of molecules in constant, random motion. P arises from collisions with container walls. No attractive or repulsive forces between molecules. Collisions elastic.
