Pressure and Volume relationship

Click For Summary
SUMMARY

The discussion centers on Boyle's Law, which states that pressure and volume are inversely proportional when the amount of gas and temperature remain constant. Participants clarify that increasing pressure in a closed system, such as a balloon, without adding gas or altering temperature leads to a decrease in volume. Misunderstandings about gas behavior under varying conditions are addressed, emphasizing the importance of Boyle's Law in explaining these phenomena.

hey!

Pressure and Volume are inversely proportional to each other
When you decrease the volume, the pressure increases.
However, when you increase the pressure, it seems to me that the gas molecules want to spread out more and the volume would increase, but boyle's law says that it should decrease because they are inversely related.
What is wrong in my thinking?
 
Chemistry news on Phys.org
Boyle's law applies only under conditions where the amount of gas molecules and the temperature of the gas remain constant.

So, let's say you have a balloon full of gas. How would you increase the pressure in that balloon without adding gas molecules or changing the pressure?
