Document Summary
Gas: expands to fill its container, particles are randomly arranges, disorganized, and far apart, density: low (<0. 01 g/ml, particle movement is very fast, no interaction between particles. Liquid: fixed volume that takes the shape of the container it occupies, particles randomly arranged but close, density: high (~1 g/ml)a, particle movement is moderate, strong interaction between particles. Solid: a definite shape and volume, particles in a fixed arrangement of very close particles, density: hight (1-10 g/ml, particle movement is slow, very strong interaction. Boyles law: decrease volume and pressure increases, p1v1 = p2v2. Boyles law and breathing: to inhale: The rib cage expands and the diaphragm lowers. This increases the volume of the lungs. Increasing the volume causes the pressure to decrease. Air is drawn into the lungs to equalize pressure: to exhale: The rib cage contracts and the diaphragm is raised. This decreases the volume of the lungs. Decreasing the volume causes pressure to increase.
