Explain Boyle's pressure-volume relationship in terms of the kinetic-<br>molecular theory ​
Troyanec [42]

Answer:

The pressure and the volume are inversely related in Boyle's Law. In Kinetic theory pressure is created by the collision of particles. If the volume is greater the number of collisions and pressure will be less. So volume and pressure are inversely related if the temperature and total kinetic energy is kept constant.

Explanation:

hope this to help you
