CSEC CHEMISTRY NOTES ON SOLUBILITY OF COMPOUNDS IN WATER and SATURATED SOLUTION Reference: Chemistry‚ a Concise Revision Course for CXC by Anne Tindale From Chemistry for CSEC by Tania Chung-Harris and Mike Taylor Factors that influence solubility Temperature * The solubility of solids in liquids generally increases as temperature increases. * The solubility of gases in liquids generally decreases as temperature increases. (gases are less soluble in warm water than in cold water)

exams—why they were doing that certain exam and what they were looking for. I saw many exams in my time of job shadowing‚ but here are a few that really stuck in my head. One of the first exams that I saw was a Barium Swallow. This is where the technologist gives the patient drinks liquid Barium while a Radiologist watches the image produced by the fluoroscope on the screen to check for any dilations or blockages. Another exam I watched was a Percutaneous Endoscopic Gastrostomy Tube Check. In this exam
