Physics and Honors Physics endured their Fluid Mechanics exam today. Performances ranged from FANTASTIC! to oh dear...This chapter was problematic due to the intrusion of snow days, professional development days and midterm week, so if your score was not the greatest don't feel too bad - just make sure the next exam is shows strong improvement.
Physical Science topped off their discussion of phases of matter with a few demonstrations and video clips of the gas laws and properties of plasma. On Monday, we turn our attention full force to phase changes, starting with the lab determining the heat of fusion of water. Every material has a characteristic amount of heat that is required to cause a phase change for a fixed amount of mass. For the solid-liquid phase change it is the heat of fusion; for the liquid-gas phase change it is the heat of vaporization. Plan on the exam for this unit falling towards the end of next week.
