I didn't know that they were, but if you need a mechanism maybe the heat "digests" normally indigestible carrot matter. There are certain chemical bonds that humans cannot "digest" (break apart), and maybe the heat breaks those bonds.

The difference in potassium content between cooked and raw spinach is that cooked spinach has a higher potassium content than raw spinach. Cooking spinach can increase the availability of potassium in the vegetable.

Provably because all the stored sugar comes out when it's cooking so it has more calories.
If both are plainly cooked, pork has more calories than chicken. For the calories in chicken, and the calories in pork, please see the page links, further down this page, listed under Related Questions.
By the slice, the medium cooked has more calories as it still contains more fat than has rendered out of the well done slices. By the ounce, well done bacon has the most calories as it weighs less than raw or medium cooked for the same reason: the fat has rendered out and it is lighter, so more slices per ounce. Well done always has the least fat. So if you want the least fat and calories per slice, always use well done.
Depends on how large it is and how it is cooked. Obviously deep-fried would contain many more calories than toasted, but a very rough estimate would be around 80~120 calories...
No, it's not true that spinach takes more energy to digest than it contains. While spinach is low in calories, it provides nutritional benefits, including vitamins, minerals, and fiber. The thermic effect of food, which is the energy required for digestion, is relatively low compared to its nutritional value, meaning you still gain energy and nutrients from consuming spinach.
There are many different sauces. Some contain more calories than others do. It depends on the ingredients used to make the sauce and the weight/amounts of those ingredients.
Possibly. If the hamburger was cooked in something caloric, say, fried in a pan on the stove top with oil, the cooked hamburger could possibly have more calories, especially if it was a relatively lean patty to begin with. Your cooked hamburger would have most of the calories of the raw patty plus that of the oil
Fresh young chard can be used raw in salads. Mature chard leaves and stalks are typically cooked or sauteed; their bitterness fades with cooking, leaving a refined flavor which is more delicate than that of cooked spinach.
