As temperature rises water becomes less polar and , in effect , a better solvent for
non - polar compounds ( Sangster , 1997 ) . The change in water could lead to
both higher enthalpy ( less energy in bonding ) and higher entropy ( less orderly
...

( 1970 ) observed a decrease in Log K between butteroil and water as
temperature was raised from 40 to 80° C . Log K was also less in a milk salt
solution ( 0 . 6 % solids buffered at pH 6 . 5 ) than in water . Flavor release is an
additional topic ...

However , a more polar compound , like 1 - propanol , is less affected by this
change in temperature , as cooling from 40 to 10° C increases the concentration
by 14 % . Even though 1 - propanol ' s Log Kmw has a greater dependence on ...
