four properties of water
the energy needed to heat substances by a particular amount called
specefic heat
which atoms are positive
hydrogen
how much of our water on earth is drinkable
3%
what happens to living things such as plants and animals, if they don't get enough water
animals get dehydrated and plants wither. This will prevent them from functioning
molecules of a substance that stick together is called
cohesion
which atoms are negative
oxygen
how much if our body is made up of water
70%
why is water a much more effective coolant than alcohol for the body
it doesn't dissolve as quickly
molecules of different substances that stick together is called
adhesion
what is polarity
anything that has a positive charge on one end and a negative on the other
How much of our water drinkable water is frozen in polar icecaps
75% of 3%
why is it important that ice floats instead of sinking
it wouldn't be able to melt and would kill all marine life
what are the 4 properties of water?
adhesion cohesion specific heat and solvent
why is water known as a universal solvent
dissolves almost everything
what are one of the ways water plays a role on earth
influencing weather+ shaping earth's surface
why is it important for us to protect our water
we have a limited amount of drinkable water, so we must keep it clean for our health
a liquid that dissolves substances is called a
solvent
what are the 3 states of water? be able to draw molecules
solid, liquid, gas
