Authoritative PPT Summary
"Water Frozen" PPT courseware on changes in temperature and water
Research purposes
The volume of water affects the solidification of water.
The effect of aqueous solutions with different solutes on the coagulation of aqueous solutions.
Effect of solute particle size on freezing of aqueous solutions.
Experimental process (1)
Take four different volumes of water, 10cc, 50cc, 100cc, and 150cc, put them into a beaker, and observe how the water freezes.
Results: 1. 10 cc of water solidifies fastest, followed by 50 cc, 100 cc, and 150 cc.
Experimental process (2)
Results: The aqueous solution with 5 grams of salt solidified fastest, followed by 10 grams, 20 grams, and 30 grams of salt.
Experimental process (3)
Results: The aqueous solution with sugar solidified fastest, followed by the aqueous solution with MSG, pepper, and salt.
Experimental results
Put the water in the refrigerator. The smaller the volume of water you put in, the faster it will solidify.
Put aqueous solutions of different concentrations into the refrigerator. The lower the concentration, the faster the solidification speed.
Aqueous solutions with different solutes solidify at different speeds. Aqueous solutions with sugar solidify faster than MSG, pepper, and salt.
Add sweet potato particles of different sizes to the water. The smaller the particles, the faster the water solidifies; the larger the particles, the slower the water solidifies.
Summary of this lesson
The size of the volume affects the freezing of water. The smaller the volume, the faster it freezes.
Concentration also affects the solidification of water. The lower the concentration, the faster the solidification.
Different solutes cause different aqueous solutions to solidify at different speeds.
The size of the particles put into the water will affect the solidification of the water. The larger the particles are, the slower the water will solidify.
after class homework:
Qualified students can go home and selectively practice the experiments taught by the teacher
