Interactions of water with cadiant energy

-Our climate, like most coastal climates, is fairly reqular, mild, and is colled "temperate"
-The reason for this our proximity to the water
-Water heats up and cools down much more slowly than air does
-This is due to water having a very large specific heat capacity
-Specific heat capacity tells us how much energy (mesured in "Joules") is needed to change the temperutuer of one gram of substanvce by one degree celcius.
-The equation we use for it is Q = MC’T

where:
Q = Heat (mesured in Joules)
M = mass of substance (in grams)
C = the specific heat capacity constant of this substance (J/g‹c)
ƒ’T = change in temperature (Ž)


water
Cw = 4.18 J/gŽ
Mw = 1.0 g
ƒ’Tw = ?
Qw = 10 J
ethanal
Ce = 2.46 J/gŽ
Me = 1.0 g
ƒ’Te = ?
Qe = 10 J
