Welcome To Whitehall Township Whitehall Township is located in the center of the Lehigh Valley. The Township is one hour north of Philadelphia and an hour and half from New York City.
SALINITY OVERVIEW Salinity is the concentration of dissolved salts in water, usually expressed in parts per thousand (ppt). Objects float higher in salt water than fresh water because salt water is denser (heavier per unit of volume).
salt water has a higher salinity than fresh water Stephanie arranges a layer of wet sand in a metal tray. She covers the tray with plastic wrap and warms the tray over a hot plate. Soon beads of water form on the plastic wrap. As the drops become largers, they run together and drip onto the sand. How would Stephanie best describe the process shown by this model?
