Bellringer: look over your 6.1 notes

In your own words, explain what 6.1 is about.

Multiple Choice

Why is water considered a unique liquid compared to other liquids?

• Because of its polarity, expansion as a solid, neutral pH, and high specific heat

• Because it is always found in liquid form

• Because it has a low specific heat

• Because it is non-polar

Multiple Choice

Why does ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Multiple Choice

Why is water called a polar molecule?

• Because it has a positive end and a negative end
• Because it dissolves a lot of substances
• Because it is essential to life
• Because it is always very cold

Multiple Choice

How does the shape and electronegativity of a water molecule contribute to its ability to bond with other water molecules?

• The shape allows water molecules to repel each other

• Electronegativity causes water molecules to attract each other

• Water molecules have no charge differences

• The shape makes water molecules neutral

Explain how cohesion and adhesion are similar and different, using examples from everyday life.

Multiple Choice

What is it called when plants give off water vapor as a waste product?

• condensation
• evaporation
• sublimation
• transpiration

Multiple Choice

As a part of the water cycle, water from Earth's surface enters the clouds and finally falls back to the ground in the form of rain. What is the correct sequence of processes water undergoes?

• Evaporation, Condensation, Precipitation

• Precipitation, Condensation, Evaporation

• Condensation, Evaporation, Precipitation

• Evaporation, Precipitation, Condensation

Multiple Choice

What is the main difference between infiltration and runoff in the movement of water?

• Infiltration is water seeping into soil, runoff is water flowing on the surface

• Infiltration is water flowing on the surface, runoff is water seeping into soil

• Both refer to water flowing on the surface

• Both refer to water seeping into soil
