WebPure water boils at 100°C at normal atmospheric pressure. As solute molecules are added to water, the boiling point increases. You could heat each of the liquids and … WebObjective: The objective of this experiment is to determine the freezing point depression and boiling point elevation of water by addition of sodium chloride, and to explore the osmosis process pass through the membrane of deshelled un-cooked eggs.

Webone with saltwater), you can do the controlled experiment to see which one evaporates faster. The vapor pressure of saltwater is less than that of pure water at the same temperature. At the air-water boundary, water molecules are constantly flying off of the surface and falling back. Some manage to Web5. Check temperature of water every 30 seconds. Continue till the water boils and temperature remains steady for some time. That temperature is the boiling point of water. Repeat the experiment with Sugar solution and Salt solution. Record the temperature every 30 seconds on the table. Thus we can find which liquid has the highest boiling point ... mobil his
