Properties of Water ~ Study Guide [Review 2023 ~ Team O]

The tendency of water molecules to stick together is called ___________.

(example: water dome on the waxed paper)

The tendency of water molecules to stick to other objects is called __________.

(example: water sticks to the side of a graduated cylinder)

The ability of water to move upward through narrow tubes is called _________.

The water properties of cohesion and adhesion work with water property.

(example: blood moves through the capillaries in our body or the flower experiment)

Water is known as the __________ __________ because it dissolves so many substances.

(examples: mixing salt or ice tea mix into a glass of water, making lemonade, making hot cocoa, etc.)

True or False: Water is made up of atoms bonded to form molecules.

The chemical formula for water is _______. There are two (2) hydrogen atoms & one (1) oxygen atom that make up water.

A molecule that has electrically charged areas is called a ____________ molecule. Water is a ________ molecule.

Each hydrogen atom has a slight __________ charge.

A oxygen molecule has a slight _________ charge.

___________ __________ is the amount of heat it takes to raise the temperature of a substance by one degree Celsius.

Because of specific heat, large bodies of water heat up/cool off more ___________ than nearby land [ex. sand].

In comparison to water's specific heat, land (sand) will heat up and cool down much ____________ than water.

The density of water is ___________.

When an object’s density is less than water, the object will _______.

When the object’s density is greater than water, the object will ________.

Ice is _________ dense than water and as a result, ice will float/stays on the surface.

As water temperature decreases, the weaker hydrogen bonds begin to hold the negatively-charged ________ atoms apart, forming a rigid crystal honeycomb structure we call ice.

Since ice has more volume, it has a lower density than liquid water. This causes ice to float in water!

When mixing the blue salt water and the red freshwater, we learned freshwater is able to “float” on saltwater because saltwater is _______ dense.

The substance that dissolves [ex. sugar] to form a solution is called a __________.

A mixture that forms when one substance dissolves another is called a _________.

The substance that does the dissolving [ex. water] is called a __________.

Which type of change occurs when the starting state is a liquid and the ending state is a gas? This happens around 100 degrees Celsius.

Which type of change occurs when the starting state is a gas and the ending state is a liquid?

Evaporation occurs as water molecules __________ energy and it occurs at the surface of a liquid. Water is changing from a liquid to a gas.

An example of evaporation is air drying your wet hair.

________________ occurs as water molecules slow down changing from a gas to a liquid.

An example is when your breath clouds up a cold window.

____________ is the only substance on Earth that commonly exists in all of its different states (solid, liquid, or gas).

The percentage of the Earth's water that is fresh water is ______?

The energy for the water cycle originally comes from the ____________.

Water that falls to the Earth as rain, snow, sleet , or hail is called ______________. Water is returned to the Earth's surface from the atmosphere.

The four factors that affect the rate (speed) of ___________ are temperature, surface area, humidity, and wind speed.

The rate of evaporation ______________ with an increase in temperature.

The amount of water vapor present in the air is called humidity. The rate of evaporation ____________ with an increase in humidity.

The rate of evaporation ______________ with an increase in surface area.

Evaporation increases with an ______________ in wind speed.

The process(es) of evaporation, precipitation, and condensation are involved with the _____________.
