Titles.
06:31:59 Narrator lecturing on water & its composition in front of chemical laboratory glass equipment. Battery used for direct current to break down water w/ acid w/ gases given off.
06:32:43 Title Boiling of Water. Stoppered flask & mercury tube used to measure. CU of thermometer & steam bubbles. CU Steam, water vapor, seen as it leaves the outlet. Closed outlet tube & thermometer shows that boiling point is increased. Vacuum pump used to lower boiling temperature.
06:34:21 Title: Distillation of water. Water jacket over condenser tube, water vapor & distilled water dripping from tube.
06:35:02 Title: Solubility of gases in water. Water poured into beaker. CU clock with speeded up hands moving from 3 to 4 o’clock. Bubbles of gas from dissolved air. CU Gold fish swimming.
06:35:38 Opening bottled water & gasses under pressure fizzing out.
06:35:46 Title: miscible and immiscible solutions. Pouring water into beaker; adding alcohol to make to make a miscible solution compound. Oil and water mixed making an immiscible solution; CUs of several in containers. MCU of washing hands in soap.
06:36:50 Title: Solution and crystallization. Solid copper sulfate dissolved into water. Saturated solution shown, then evaporate part of it & crystals are formed. Cooling of saturated solution making crystals; precipitate seen on filter paper.
06:38:40 Title: Supersaturation. Crystalization is shown in test tube.
06:38:10 Title: Water is used as a standard of comparison. Comparison of weight & volume using water as the standard & specific gravity measured. Heat of fusion of water is measured; calorie is defined. Heat of vaporization shown. CU opening icebox. Ice added to container.
06:41:03 Title: Heat of vaporization. Heating liquid over bunsen burner.
