| First Law of Thermodynamics | show 🗑

| Second Law of Thermodynamics | show 🗑

| Third Law of Thermodynamics | show 🗑
|

| How does temperature affect entropy? | show 🗑
|
||||
| When will an increase in temp/energy have a greater impact? | show 🗑
|
||||
| What affect does pressure have on entropy? | show 🗑
|
||||
| show | equilibrium, because it is the lowest possible free energy point
🗑
|
||||
| show | Wmax = G; maximum possible useful work obtainable from a process at constant temp/pressure; equal to the change in free energy
🗑
|
||||
| What is deltaG? | show 🗑
|
||||
| What is "wasted" energy? | show 🗑
|
||||
| Reversible Process | show 🗑
|
||||
| show | universe is different after cyclic process is performed; system returns to its original state, but surrounds has to furnish a net amount of work; all real processes are irreversible
🗑
|
||||
| show | when gas+O2 combust, the energy in bonds spreads over the surroundings as thermal energy instead of being concentrated; the thermal energy is harder to use. the energy has become more disordered (increase in entropy) and less useful (energy crisis)
🗑
|
||||
| deltaS of surroundings | show 🗑
|
||||
| show | occurs without outside intervention
🗑
|
||||
| show | depends on the number of positional microstates (spatial configurations) that yield a specific state
🗑
|
||||
| show | deltaS of universe = deltaS of system + deltaS of surroundings; deltaS universe = -deltaG / T in K

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
