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
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.
Where will we find that we have warmer winters and cooler summers due to water's high specific heat capacity?
Near the coast
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
Water is sticking to other water molecules is known as?
Cohesion
Water has a high heat of vaporization. What does this mean?
It requires a lot of energy to convert it from a liquid to a gas
condensation
The percentage of our bodies made up of water.
about 60 -70 %
What is the name for bonds between water molecules?
Hydrogen 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 given off by the leaves of plants. This is called
transpiration.
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
How do fish survive in frozen bodies of water?
Only the top of the water is frozen, so the fish can still receive sunlight and swim in the water.
Precipitation that reaches Earth's surface, flows over land, and reaches lakes rivers and oceans is called
surface run-off
