Spontaneous Process | one that proceeds in a given direction with out any outside intervention
🗑
|
||||
Non-Spontaneous Process | Occurs only as long as energy continually added to system
🗑
|
||||
Spontaneity | Depends on the dispersion of energy is added to system
🗑
|
||||
Second Law of Thermodynamics | The total entropy of the universe increase in any spontaneous process
🗑
|
||||
Entropy (S) | a measure of distribution of energy in a system at a specific temperature
🗑

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.
