Properties of Water by Bahrami https://padlet.com/farideh_bahrami/ows0kvlw5291 en-us 2018-10-12 21:59:08 UTC 2026-06-25 06:02:03 UTC hello@padlet.com Mrs. Bahrami 10/13 farideh_bahrami https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292362049 Claim:Water exhibits the property of polarity .
Evidence:Water droplets on the wax paper were attracted to each other.
Reasoning:Because water is a polar molecule. That is, it has one side that is partially positively(H+) charged and one side that is partially negatively(O-) charged. When two water molecules get close together, the polar forces work to draw the molecules together through hydrogen bonding . Therefore, water droplets tend to attract to each other. ]]> 2018-10-12 22:02:54 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292362049 farideh_bahrami https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292372638 2018-10-13 01:01:04 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292372638 Capillary action farideh_bahrami https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292374339 Thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances). ]]> 2018-10-13 01:29:19 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292374339 farideh_bahrami https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292374531 2018-10-13 01:32:35 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292374531 Density : farideh_bahrami https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292374612   Ice floats on water because it is less dense.

Reasoning: Water forms hydrogen bonds this s because the attraction between water molecules this is what allows the paperclip to float and the dome to form on the penny.]]> 2018-10-15 15:20:44 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876098 George little https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876107 2018-10-15 15:20:45 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876107 Mary Weaver and Travis Lengen 10/15/18 https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876303 Claim: Water displays the property of surface tension 
Evidence: The paper clips could float on top of the water in the dish. Surface Tension 
Reasoning:  It would not break the hydrogen bond because water forms hydrogen bond water molecules are attract to each other and that causes surfaces tensions and allows the paper clips to float. ]]> 2018-10-15 15:21:05 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876303 Sebastian Rocha https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876349 Claim: Water exhibits the property of Cohesion.
Evidence: Water Groups together and sticks together on top of the penny.
Reasoning: Because water can have as many as 4 hydrogen bonds at the same time, the water molecules are attracted to each other,  and they therefore group up on top of the penny.]]> 2018-10-15 15:21:09 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876349 Beti D and Robyn F 10/ 15/18 https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876416 Claim- Hydrogen and oxygen atoms are attracted to each other due to the negative and positive charges
Evidence- Water droplets on the penny bonded and formed above the penny
Reasoning- because negative charge is oxygen and positive charge is the hydrogen and opposites attract they bond together.]]> 2018-10-15 15:21:16 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876416 Toby & George 10/15/18 https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876472 Claim: Water exhibits the property of cohesion.

Evidence: The paper clips floats on the surface of the water.

Reasoning: The property of surface tension is demonstrated because the molecules at the surface of the water form stronger bonds to keep the paper clip afloat.]]> 2018-10-15 15:21:24 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876472 Emily 10-15-18 elin21 https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876534 Claim: water is  more dense than ice

Evidence: Ice floats on water

Reasoning: When water freezes (ice) the  water molecules form a structure maintained by hydrogen bonding. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density

evidence: paperclips float in water 

reasoning: because water forms hydrogen bonds water molecules are attracted to each other and that attraction causes surface tension and allows for the paperclip to float]]> 2018-10-15 15:21:32 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876537 Robert Murphy https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876540 Claim: the ice will float on water
Evidence: The ice floats on top of the water
Reasoning: The water molecules are less dense due to hydrogen bonding. The way the hydrogen bonds are spaced it causes the water to become less dense.]]> 2018-10-15 15:21:33 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876540 Grace, Melissa, and Conner, https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876645 Claim: Water can exhibit surface tension
Evidence: paper clips floating on water.
Reasoning: Because water form hydrogen bonds. These bonds helps water molecules be attracted to each other and build beads to allow small things to float. ]]> 2018-10-15 15:21:43 UTC https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876645 Ben Sroka 10/15 bsroka https://padlet.com/farideh_bahrami/ows0kvlw5291/wish/292876745 Claim: Surface Tension
