To cook rice, by whichever method one uses, needs water at or slightly less than boiling point of water – 100degC. When boiling, temperature of water stays constant. With the water at this temperature, the rice grains absorb water (get ‘cooked’).
What happens to rice when boiled?
Cooking does two things to the rice. First, it hydrates the rice grain (adds moisture to it), making it swell and increase in size. Second, the heat cooks the rice grains, making them soft and slightly gelatinous. Properly cooked rice has a moisture level between 58% and 64%.
Does rice go in after water boils?

Why does my rice get sticky?
When the now starch-coated rice hits the boiling water, the starch blooms and gets sticky. As the water is absorbed, and the rice grains get closer and closer together, they will begin to stick to one anther and form large clumps. The very simple solution is to rinse.
Why is my rice mushy?
Mushy or soggy rice is simply overcooked rice that has absorbed too much water. Water over-absorption causes the rice grains to split open, ruining the texture and creating a starchy, gummy result.

Is cooking rice exothermic or endothermic?
Cooking of rice is both irreversible and endothermic reaction. i.e once cooked rice cannot be made rice back and the rice absorbs heat from the external sources and utilizes for its cooking so it is endothermic.
How is cooking rice a chemical reaction?
Why does rice get soft when cooked? Rice goes from crunchy dryness to pillowy goodness via a chemical process called gelatinization.

Does draining water from rice reduce carbs?
Nearly 90 percent of the calories in cooked rice come from carbs. Boiled rice is sometimes cooked in more water than it requires; afterward, the excess water is drained and thrown away, which can result in less starch and water-soluble nutrients in the rice.

A scorched pot probably means that the burner was too high. Put your burner on the lowest setting—the steam should be doing all the work, not the burner. Also check that you’re using a heavy-bottomed pot, like this sturdy saucepan—a thin pot will expose the grains to too much direct heat.
