PHYS 131 Chapter Notes - Chapter 1: Ideal Gas Law, Altimeter, Pressure Measurement
Document Summary
Understand why the pressure in a liquid at depth h is given by equation (14. 4) and the direction of the force on a surface due to uid pressure in a uid (figure 14. 10) 14. 1 by the end of this section, you will be able to: Describe the characteristics of the phases of matter at the molecular or atomic level. Compare and contrast the densities of various substances. Explain the relationship between pressure and force, calculate force given pressure and area. There is a signi cant force between these molecules. Rigid and have speci c shapes and de nite volumes. The atoms/molecules are in close proximity to each other. Take a form determined by the nature of forces between the molecules. Requires a large force to change the shape of a solid; produces small displacements in atoms/molecules of lattice- solid maintains its shape. Structure: three-dimensional lattice is represented as molecules connected by rigid bonds.
