Science by Correspondence: Extreme Temperatures
Description
Can cold water actually freeze faster than hot water, and how does the surrounding air influence the speed at which liquids change their temperature? Dr. Erez Garty presents experiments and answers viewers' questions regarding thermodynamics, freezing points, and heat conduction. Join us on a scientific journey into the fascinating phenomena that occur at the interface between heat and cold.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
