Thermal properties of water Flashcards
what do you have to do to water to make it change phases
add/remove heat
3 phases of water
solid, liquid, gas
during the ice stage…
molecules are packed together
heat capacity
amount of heat it takes to raise 1gram of a substance by 1 deg. celcius
high heat capacity
requires a lot of heat to change a substance
why does water have a high heat capacity
hydrogen bonds can move freely
why doesn’t the ocean change temp. very often
oceans absorb/ release huge amounts of heat without much change with little change in temperature.
where do storms typically move
W to E
does land have a large heat capacity
Land has a very low heat capacity
do oceans have climates
The ocean has a very moderate temp. it does not change very much at all throughout the year
thermal inertia
because of this the (H bonds) dont want to change and take a very long time to heat up and cool down
what are the eastern margins regulated by
Not by the oceans, they are regulated by the wind.
what is the average ocean temp
20 deg. c
hottest temp recorded
129 deg. f (death valley)
coldest temp ever recorded
-128.2 deg f (antarctica)
