Question | Answer |
definition of excellent solvent | polar molecule. If substance has a charge then water will break up |
how excellent solvent helps living things | helps with chemical reactions, dissolves nutrients and gasses. example fish breathing underwater |
high specific heat definition | amount of heat needed ti raise 1 ml of a substance 1 degree celcius |
how high specific heat helps living things | helps water resist rapid temperature change. |
high heat of vaporization definition | energy needed to change a liquid into a gas |
how does high heat of vaparization help living things | helps to maintain body temperature. cools or warms organisms on hot or cold days |
high heat if fusion definition | amount of heat that must be removed from water in order for water to freeze |
how does high heat of fusion help living things | gives aquatic organisms more time to adjust to the cooling temperatures |
water is less dense than a solid definition | water expands when freezing because becoming more organized. Bottom of lake 4 degrees Celsius because most dence |
how does water is less dense than a solid help living things | keeps ponds under ice a good temperature, freezes top to bottom |
capillary action definition | the ability of water to soak into objects that have a charge (cohesion=1 substance adhesion= 2 different substances) |
how does capillary action help living things | it helps transport water to the upper most leaves of trees/plants |
surface tension definition | water attaches to itself with hydrogen bonds and forms a skin on the surface that can support small objects heavier than water |
how does surface tension help living things | helps small insects to stay on top of the water instead of sinking in |
