Talk to another person and they say I'm about to make a huge mistake by checking it at all. Bignik get a surprise! This fountain creates a fine mist of the very hot oil, this greatly increased surface area coupled with the already hot oil causes it to ignite which then ignites surrounding droplets until the entire batch of oil that was displaced from the pot is a huge fireball. Oil boils at a higher temperature than water which means that when water is poured into boiling oil it is heated to, and past, the boiling point very quickly. 2x above the pressure rating will turn your water heater into a rocket. What keeps the rate of burning in check is the rate at which oxygen can reach the burning oil surface. This really isn't much of an answer; it would be better if you could expand this to cover what heat transfer does (e.g., the rapid change indicates X). More precisely, its due to the difference in their temperature and due to vigorous transfer of thermal energy from hot oil to cold water where water instantly changes its state into vapour. Normally, your water heater shuts off or releases the built-up pressure through a safety valve. According to the textbooks, these reactive electrons rip apart the surrounding water molecules to release hydrogen gas and heat.

Who are the famous writers in region 9 Philippines? Why? Water explosion is considered to be environmentally friendly if the heat is generated â¦ However if these safety mechanisms fail, the pressure can mount until the tank eventually gives way. The bubbles explode because they superheat. is created instantaneously at the oil-water interface. Actually, organic oil may smoke, i.e., decompose chemically, much before it boils, but nevertheless at very high temperature such as $191^\circ\;\mathrm{C}$ for olive oil (extra virgin, higher for other qualities). Thus hot oil may mean much hotter than the boiling point of water. The steam What is the application of rev in real life? Hence I want my activity free from downvotes. The oil is analogous to the container that holds the explosive (water-->steam) . Why don't libraries smell like bookstores? Once there it evaporates and pushes the oil out into the air. The water heats up and expands as it is falling through the oil, due to density. The liquid water changes phase when heated above the boiling point, namely it becomes a gas. There is a point the balloon will get to that it will no longer be able to expand. Investigators were looking for any hot work being performed during the explosion â¦ However, he was never told to put the water in first â either verbally by the pool shop, or on the chlorine packaging.

I check one website and it says to check it every 6 months. Always fun to conduct new experiments. Even though water and steam are in equilbrium at 100°C there is a potential barrier to formation of a steam bubble. relative density, water being denser than oil. Chemistry has tricks for getting oil and water to interact. its pretty much the same. The effect depend on $200^\circ\;\mathrm{C}$: $197^\circ\;\mathrm{C}$ for olive oil, $246^\circ\;\mathrm{C}$ for corn oil, MAINTENANCE WARNING: Possible downtime early morning Dec 2, 4, and 9 UTC….

Hot sauce exploded. ; Water temperature should NEVER exceed 212ËF. And while that does work, you might be creating an excellent breeding ground for all sorts of icky things. Let me know if you edit by replying to this comment. Oil is also less dense than water meaning that the water will sink to the bottom of the pot. What Happens When You Add Water to a Grease Fire The polar water molecules and nonpolar oil molecules want to keep as far away from each other as possible. I just got a home maintenance book that says hot water heaters can explode if the pressure release valve becomes inoperable. And because water is denser than oil, it sinks right to the bottom of the pan â underneath the grease fire, Dr. Biberdorf explains. Some people lower the temp on their water heater to save energy. Namely, if water would stay on top, it would just evaporate, but as it sinks into the oil (oil goes on top of water) the rapid volume change results in an explosion "ejecting" oil. Why does hot water clean better than cold water? For oil, the boiling point varies, but is very often above $200^\circ\;\mathrm{C}$: $197^\circ\;\mathrm{C}$ for olive oil, $246^\circ\;\mathrm{C}$ for corn oil (depending on quality, it can vary significantly), and around $300^\circ\;\mathrm{C}$ for refined motor oil.
