The discussion centers on the relationship between volume (V), pressure (P), and temperature (T) in gases, governed by the ideal gas law, which states that PV/T remains constant for a given amount of gas. Participants confirm that decreasing volume while keeping temperature constant results in increased pressure, and vice versa. Additionally, increasing temperature while maintaining volume leads to a rise in pressure, highlighting the dangers of heating pressurized containers, such as aerosol cans. The principles discussed are foundational to understanding gas behavior in various applications.

Try leaving anyone thing alone and change one thing, and you can see what happens to the third thing; for example, leave T alone, decrease V, then P must increase. Does it make sense? Does squeezing a gas into a smaller container make its pressure go up? Check.
Why it's dangerous to throw an aerosol can into a campfire. Leave V alone, and increase T, so then P must increase. Kaboom!
