Why is it that if I leave temp high, water alone boils without spilling out of the pot, but if I add something to it (like pasta, chai mix, etc) and leave it on high, it eventually boils over and spills everywhere?
In: Chemistry
Boiling those things in water causes ingredients to leech into the water, like starch from pastas.
Those added things increase the surface tension on the water allowing bubbles to form and not immediately pop. The bubbles build up on top of each other until they flow over the side of the pot.
Regular water doesn’t form bubbles very well and they ussually pop quickly. So the bubbles pop before they can build up.
