Since the vapor pressure increases with temperature, it follows that for pressure greater than 760 … feline cataracts symptoms

"WebStarches increase this surface tension making the bubbles more elastic/pliable (essentially creating a foam), thus requiring more force for them to burst. This makes the bubbles last longer which allows them to build up and eventually boil over. It's more likely to occur with anything starchy like rice and pasta.

When water is heated in a microwave, it may remain undisturbed during the heating process so that there are no nucleation sites around which bubbles may form. The superheated water may appear to be cooler than it really is since …

WebFrozen boiled water does not boil faster than regular water. In fact, frozen boiled water takes longer to boil compared to unfrozen water because it must first thaw before reaching its boiling point. When water is boiled, it reaches its boiling point of 100°C (212°F) and turns into water vapor or steam. However, frozen water (ice) is at a ...

WebBoiling occurs IF AND ONLY IF the vapour pressure of the water overcomes the external vapour pressure. So it's not the pressure of the water itself, it has to do with the vapour pressure. So when water boils at 100 C at 1 atm, this means that only at 100 C does the vapour pressure of the water overcome the external vapour pressure.
