When one mole of liquid water is frozen in a freezer at –10°C, what are the relative values of ΔSsys and ΔSsurr? Is the reaction spontaneous?
|
ΔSsys < 0, ΔSsurr > 0, spontaneous |
||
|
ΔSsys > 0, ΔSsurr < 0, equilibrium |
||
|
ΔSsys > 0, ΔSsurr < 0, non-spontaneous |
||
|
ΔSsys < 0, ΔSsurr > 0, non-spontaneous |
||
|
ΔSsys > 0, ΔSsurr < 0, spontaneous |

9-16 When liquids freeze the density changes, which means that the volume changes as well. Water is one of the few liquids that expand when frozen. That is why it is a bad idea to put water in the freezer in a sealed container. Pete decides to test this idea. He sticks an unopened soft drink can in the freezer. Given: In liquid form the soft drink has a density of 1.11 x 103 kg/m3, more dense than water because...
