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?
A student is recording the volume of a liquid. What unit of measurement will she use?
What is 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 1?
In the lab, what tools are commonly used to measure mass?
What is a scale or triple beam balance?
In the lab, what tools are commonly used to measure volume?
What is a beaker or graduated cylinder?
Snow, rain, sleet, hail. These 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 is grams?
Clouds and fog are examples of what part of the water cycle?
What is condensation?
Water molecules tend to "stick" together because of 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.
What is g/ml or g/cm3?
Lakes, rivers, streams and puddles are examples of what part of the water cycle?
What is accumulation?
This property describes tightness across the surface of water, caused by the polar molecules pulling on one another.
What is surface tension?
What can increase the rate of diffusion? (think about making a cup of tea with a tea bag.)
What is temperature?
When two or more atoms bond together, what us made?
What is a molecule?
This system of measurement is used in science.
What is the metric or SI system?
What part of the water cycle is not visible?
What is evaporation or transpiration (water vapor)?
