The K12 lessons define [...] as the tendency of any system to move toward maximum randomness. | The K12 lessons define entropy as the tendency of any system to move toward maximum randomness. |
Entropy is really energy that can not be used to do any [..]. | Entropy is really energy that can not be used to do any work. |
The symbol for Entropy is a [...]. | The symbol for Entropy is a capital S. |
A [...] entropy change means that entropy has increased. | A positive entropy change means that entropy has increased. |
a liquid has [more/less] entropy than a solid | a liquid has more entropy than a solid |
Entropy and Enthalpy determine whether a reaction is [...] or not. | Entropy and Enthalpy determine whether a reaction is spontaneous or not. |
solid -> liquid -> gas : entropy [-es] | solid -> liquid -> gas : entropy increases |
break something into smaller pieces: entropy [-es] | break something into smaller pieces: entropy increases |
speed up movement of particles: entropy [-es] | speed up movement of particles: entropy increases |

a [...] entropy change favors a spontaneous reaction, but enthalpy is also a factor | a positive entropy change favors a spontaneous reaction, but enthalpy is also a factor |
Gibb's [...] energy combines the changes in both enthalpy and entropy | Gibb's free energy combines the changes in both enthalpy and entropy |
A [...] change in Gibb's free energy means the reaction will be spontaneous. | A negative change in Gibb's free energy means the reaction will be spontaneous. |
