Properties I
This property of water allows a pin to float on the surface of water.
What is "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 mass/volume? (Mass divided by volume).
A student is recording the volume of a liquid. What unit of measurement will she use?
What are "liters?"
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?"
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 "one?"
What is one tool that is commonly used to measure mass?
What is a "scale?"
This means that water dissolves many substances.
What is "solvent?"
Snow, rain, sleet, and hail are all examples of what part of the water cycle?
What is "precipitation?"
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?"
This unit of measurement is used to label mass.
What are "grams?"
Paula orders a cold beer and sees water begin to collect on the outside of the glass. What is this process called?
What is "condensation?"
Water molecules tend to "stick" together because of the positively and negatively charged "ends" of the molecule. So, we say it is what kind of molecule?
What is a "polar molecule?"
This refers to the movement of molecules from an area of higher concentration to an area of lower concentration.
What is "diffusion?"
This is formed when two or more atoms combine. For example, water is one.
What is a "molecule?"
This is how density is labeled (in units).
What is "g/ml" or "g/cm3?"
The process of water changing from a gas to a solid.
What is "deposition?"
This property describes tightness across the surface of water, caused by the polar molecules pulling on one another.
What is "surface tension" / "cohesion?"
This variable influences the rate of diffusion.
What is "temperature?"
A molecule consisting of more than one element.
What is a "compound?"
This system of measurement is predominantly used in science.
What is the metric or SI system?
The process of water changing from a solid to a gas.
