Properties of Water
Water has a high specific heat capacity. This means that it takes a long time to for water to heat up but also a long time to ___ once it's heated.
cool
The components of a molecule of water.
2 hydrogen atoms and 1 oxygen atom
A water molecule looks sort of like what cartoon character
Mickey Mouse
True/False: Water is the only natural substance that can exist in all 3 states of matter at normal temperatures for Earth.
Condensed water vapor that falls back to the Earth in the form of rain, sleet, snow or hail.
Why does it take longer to boil an egg on a mountain?
the altitude reduces the pressure on the water molecules
The hydrogen end of water has a
slight positive charge
True
Water sticking to other surfaces/substances is known as
Adhesion
The process of liquid water changing into water vapor due to an increase in temperature/pressure is
evaporation
The percentage of Earth's surface that is covered by water.
about 70%
The oxygen end of a water molecule has a
slight negative charge
Cohesion causes this phenomenon that allows bugs to glide on water
surface tension
The melting point of water is equal to its
freezing point
condensation
The percentage of our bodies made up of water.
about 60 -70 %
Why are water molecules attracted to each other?
because of polar bonding
This causes water to clump together in drops.
cohesion
Ice floats because
solid water (ice) is less dense than liquid water
Water vapor is the product of what process?
evaporation
Capillary action is made possible due to which two properties of water?
What type of bond is formed from the attraction between the positive end of one water molecule and the negative end of another water molecule?
a hydrogen bond
This causes water to stick to other polar substances besides other water molecules.
adhesion
What happens when liquid water molecules slow down?
they turn into a solid (ice)
All water flowing down from the environment to the oceans/rivers/streams is called
