Kinetic Theory and Phase Changes: Crash Course Physics

The video discusses the Mariner 9 mission to Mars, focusing on its use of the triple point of water as a reference for mapping. It explains the kinetic theory of gases, including the assumptions of ideal gases and the calculation of root mean square speed. The video also covers the behavior of real gases under different conditions and the concept of phase changes, including the critical and triple points. These concepts are linked to the exploration of Mars and the search for liquid water as a potential indicator of life.

How does the root mean square speed differ from the average speed of gas molecules?
