Properties of Water

Molecules

100

What is the chemical composition of a water molecule? 

H20

200

Water has how many hydrogen atoms? 

2

300

Water has how many oxygen atoms? 

1

400

Water has how many positive poles? 

2

500

Water has how many negative poles and what property is created by this pole? 

1 negative pole; polarity

Polarity

100

This is created by a free floating negative charge on the oxygen atom of a water molecule

polarity

200

Because water is polar, it dissolves other substances easily. This makes water a 

Universal Solvent

300

Because of polarity, water likes to stick to its own molecules. This creates 

cohesion

400

Due to its polarity, water molecules often stick to other surfaces or substances. This creates 

adhesion

500

The cooperation of cohesion and adhesion can lead water molecules to defy gravity and move up a surface or substance. This action is called 

capillary action

Surface tension

100

Due to polarity, the water molecules do not easily separate and this leads to a property known as 

Surface tension

200

Surface tension is imperative for life on earth, name two animals that utilize surface tension for survival

Water bugs, jesus lizards

300

We did two activities to show surface tension in action. What were these activities? 

Water on a penny, water race. 

400

Is it possible to break waters surface tension? 

Yes

500

This is one of Ms. Hawkins' favorite memes regarding surface tension. 

Swimmers before they break water's surface tension, making them look trapped under the water. 

MISC

100

Water becomes ________ dense when frozen, leading to ice floating on liquid water. 

less

200

Ice has a high _________ making it difficult to change the temperature of water. 

Heat Capacity

300

There was one video watched regarding heat capacity. Which video was this? 

Two balloons, one popping and one not due to the heat capacity of water. 

400

What property allows polar bears to hunt, fish to swim in arctic conditions, and the survival of life in winter? 

Ice being less dense than water. 

500

Water is considered a triple point for Earth. What does this mean? 

Water exists in all states of matter naturally on Earth. 

Easy

100

You cannot go more than three days without ingesting this substance

Water

200

In a salt- water solution, water is the 

Solvent

300

In a salt- water solution, salt is the 

Solute

400

These are the types of bonds present in the water molecule, holding the hydrogen to the oxygen

Hydrogen bonds

The cup and string experiment today was to show this property of water 

Adhesion
