What property causes water to climb up materials like paper?
Adhesion (water sticking to other surfaces)
Why might a strong surface tension ("water skin") be useful in a "Cell Factory’s" storage tanks?
(Possible answers based on concept: Helps contain liquids, prevents spills/leaks, could help form compartments)
Why is water's solvent power important for a "Cell Factory"?
It's vital for cleaning or mixing processes
How could adhesion (water sticking to surfaces) help transport nutrients in a "Cell Factory"?
(Possible answers based on concept: Allows water/nutrients to climb through tubes/cell walls, helps spread liquids over surfaces)
What property allows a paperclip to float on water?
Surface tension (water's "skin" holding weight)
Did salt dissolve in water? Did salt dissolve in oil?
Yes, salt dissolved in water; No, salt did not dissolve in oil
How did you measure the effect of adhesion in the lab?
By measuring how high (in cm) water climbed up chromatography paper in a set time.
What happened to the number of drops that could fit on the penny after adding dish soap?
Fewer drops fit / The cohesion decreased
What property of water describes its ability to dissolve substances like salt or sugar?
Solvent power
How could cohesion (water sticking to itself) help move materials in a "Cell Factory"?
(Possible answers based on concept: Helps form droplets for transport, allows flow in pipes/channels, helps pull water columns up)
What property was tested by seeing how many water drops fit on a penny?
Cohesion (water sticking to itself)
What happened to the floating paperclip when you added a drop of dish soap?
It sank
