ice n' salt

today in chemistry we did a lab. we used a beaker, test tube, ring stand, ice, salt, and a graphing caluclator that recorded the temperature every three seconds to make three hundered points that took fifteen minutes. we did this lab to see what the temperature would do. it started to decline then it flat lined, because it was at the freezing stage then once it turned to a solid, the temperature started to drop again.
