Second Type of Ideal Gas Law Problems

Here is an index of the other videos in Chapter 6: Gases: bit.ly/3zOPAIT In the second major type of ideal gas law problems a new value of P, V, n or T is found after a gas undergoes a change.
State 1 (P1, V1, T1, n1) to State 2 (P2, V2, T2, n2). The gas law constant R is not used during this calculation so the units of pressure and volume can be variable. However, the temperature still need to be in Kelvin. The calculation an be simplified if any of the variables are held constant during the change. A sample problem is discussed in this video.
