G. Behavior of Gases 1. Gas pressure is caused by collisions of gas particles on surfaces. 2. Pressure is measured in pascals . 3. 1 Pa = 1 N / m^2 4. Standard air pressure at sea level is 101.3 kPa … this is the same pressure as a big truck (14.7 pounds / sq. inch). 5. We normally use “atm” for problems

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.
