This question describes table sugar as the common name for the compound sucrose.
00:07
When heated to 186 degrees celsius, sucrose decomposes, in order to appropriately answer this question based upon just that small amount of information provided, you need to recognize that if a compound is going to decompose, that it has a decrease in its stability, or it becomes more unstable.
00:33
So it wants to know which statement accurately describes the stability of sucrose as it is heated to its decomposition temperature.
00:43
With only that piece of information, it says nothing about whether or not the stability is increasing or decreasing before we reach 186 degrees celsius.
00:55
However, we can assume that as we get closer to 186 degrees celsius, its stability decreases.
01:05
So the first statement says, as sucrose is heated to higher temperatures, it becomes more stable and then decomposes.
01:14
This goes against what we were talking about up here.
01:17
If it's going to decompose, it won't become more stable, it'll become less stable, so that statement is false.
01:23
As sucrose is heated to higher temperatures, it becomes less stable and eventually decomposes as 180...
