This is the property where molecules sticks to one another

cohesion

100

how can you describe what surface tension is? 

it creates a “skin” on water’s surface

100

Does water heat up quickly or slowly?

Slowly, because of its high specific heat.

100

water is made up of these atoms

1 hydrogen; 2 oxygens

100

I can speak this language

chinese/mandarin

200

what is adhesion? 

water sticks to other stuff

200

name an organism that can walk on water

lizard, water strider, some spiders, etc

Why does ice float on water?

Ice is less dense than liquid water because its molecules spread out when frozen.

200
about how many days can you go without water

3-5!

Jamuna's family consists of...

parents, twin & dog

300

through this property, plants can get water

capillary action

300

surface tension arises because of this property of water

cohesion

300

what does high specific heat capacity mean

water can absorb a lot of heat before it gets hot.

300

name at least one factor that impacts the distribution of freshwater sources 

1) climate change 2) human activity 3) natural variability 

300

this was the reason Jamuna got surgery on her right foot

I stepped out of a car :(

Explain how cohesion and adhesion work together in capillary action.

Adhesion causes water to stick to the surface and cohesion pulls other water molecules along with it, helping it move upward against gravity.

Why can a paper clip float on water even though it’s made of metal and is denser than water?


surface tension!

400

You're cooking pasta and leave a metal spoon in the boiling water. The spoon gets hot, but the water temperature doesn't rise quickly. Why?

Metal heats quickly because it has low specific heat, but water has a high specific heat, so it resists temperature changes even when heated.

400

estimate the percentage of freshwater vs. ocean water on Earth

about 96.5% ocean water, 2.5% freshwater

400

what two concerts did Jamuna attend

Kendrick & SZA, and The Weeknd

500

explain the property(s) of water involved when you spill water and use a paper towel to soak it up.

Adhesion causes water to stick to the paper fibers, and cohesion pulls more water molecules along as the towel absorbs the liquid.

500

How might adding soap impact the surface tension of water?

Soap would disrupt the cohesive forces between water molecules, weakening surface tension.

500

How do fish stay alive in the winter? 

Ice floats and forms an insulating layer, keeping water beneath from freezing and allowing them to survive.

500

Why is clean water access a global issue?

Without clean water, people face more health issues, dehydration, and poor sanitation.

I am older than my twin

Idk... lol :-)
