Pressure

Why? The concept of pressure accounts for the effect of a force applied to some surface area. The relationship between force, area, and pressure is used frequently in chemistry whenever gases are involved. This relationship is needed to decide on the strength of gas containers and delivery systems.
Learning Objectives • Discriminate between force and pressure.
• Understand the relationships among, mass, force, and pressure and their units.
• Develop understanding in solving problems related to pressure.
Success Criteria • Calculate forces and pressures.
• Analyze situations in terms of force and pressure.
New Concepts force, pressure, Newton (N), Pascal (Pa)
