properties
this property of water allows a pin to float on the surface of water
What is cohesion at the surface (surface tension)?
This is the number of hydrogen atoms in a water molecule..
What is two?
How do we calculate the density of an object or substance?
What is divide it mass by its volume?
After swimming, you leave your towel out in the sun. An hour later, the towel is dry. What part of the water cycle best describes this process?
What is evaporation?
The amount of heat needed to increase the temperature of water by 1 degree Celsius
What is high specific heat
This property of water demonstrates the attraction of one water molecule to another.
What is cohesion?
This is the number of oxygen atoms in a water molecule.
What is 1?
This is formed when two or more atoms combine. For example, water is one.
What is a molecule?
Snow, rain, sleet, hail. These are all examples of what part of the water cycle?
What is precipitation?
Water can stick to itself and other things. This is called what?
What is adhesion?
This property of water allows water to "climb" up substances.
What is capillary action?
This is the chemical formula for water.
What is H20?
This is the smallest particle of matter.
What is an atom?
Clouds and fog are examples of what part of the water cycle?
What is condensation?
This is the temperature at which water freezes.
What is 0°C or 32°F?
This property allows water to dissolve many substances.
What is universal solvent
What is a molecule that has "electrically" charged areas?
What is a polar molecule
The negatively charged particles that orbit the nucleus of an atom are known as what?
What are electrons?
What part of the water cycle is not visible?
What is water vapor or evaporation?
Water molecules are polar due to this type of bond between hydrogen and oxygen atoms.
What is a hydrogen bond?
T/F capillary action explains how water moves against the force of gravity
What is True
What is the charge on the oxygen in a water molecule?

What is a solid?
Lakes, rivers, streams and puddles are examples of what part of the water cycle?
What is accumulation?
Water's ability to dissolve various substances makes it critical in this natural process, essential for cleaning and transporting nutrients.
