Zinc – Specific Heat Capacity
It depends on the atmosphere in which zinc is heated. If Zinc metal is heated in an inert atmosphere (e.g. Argon gas), then solid zinc will get hot until it reaches its melting point, then melt, and then slowly evaporate until it reaches its boiling point, then boil and then become zinc vapor. This is a PHYSICAL change that most solids undergo. Sep 10, · Zinc doesn't become "toxic" at any temperature, but what does happen at the vaporization temperature of zinc (about ° F) is that the metal turns to a gas, such that it can be easy to inhale an overdose if you are a welder. An oven in the kitchen is for cooking food, and that's all it .
World's 1 finishing resource since No login needed: Chime right in. I was just wondering that if you get zinc so hot that the temperature reaches degrees Fahrenheit if it would give off some kind of gas that could kill you or anything.
I an doing my science project on which kind of metal gets hottest the quickest and I did not want it to get so hot and let off some kind of gas and kill or hurt people in what happens when you heat zinc whole school.
So shen if there is anyway possible that happnes could give me a response about zinc as soon as possible. Hi Brian. Best of luck with your project, and thanks for being careful! I just read that outside temperatures of over degrees have been recorded.
Your attic probably reaches in the summer. Are you sure you have that temperature right? If you were welding or putting a cutting torch on zinc, I'd worry. Or if you were eating off a zinc-plated sheet I'd worry a bit. I think your chief concern should be that nobody touches the metals and gets burned, and I'd suggest a warning sign to that effect. I have personally been quite sick by breathing the gaseous oxide of the metal in question. I was welding galvanized pipe and failed to note the direction of the wind.
I was sick for a day. I doubt that degrees would cause any problem with it. I think that your investigation zinx in the direction of "specific heat". You will find listings of how much heat energy is required to increase each type of material, by weight, dhat equal amount. I am building a fire pit using two half circles basement window wells.
They are galvanized steel and my son said that they would give off fumes that are harmful. I agreed with him but feel that a good fire would drive out the zinc. Is this true? Hi, John. As long as this fire pit is outside, which I would certainly expect, I don't think there is much of a problem.
While the heart of a hot fire is hot enough to melt the zinc, and maybe to vaporize it, I think you'd find it hard to build a fire that would vaporize the zinc except in a tiny spot, and then only on the inside wall, not the outside wall.
Welding is something else, involving way higher temperatures, and inhaling the fumes because you're staying very close yoh watch your work. Zinc is not a toxic whne but a necessary micro nutrient cold prevention tablets are actually zinc supplementsand a normal outdoor exposure to the small amount from a camp fires wouldn't worry me personally at all.
Thanks, I'll be building my fire pit and passing on the design and information. The oven is how to format annotated bibliography in word vented to the outside.
Also it would be good to know at roughly what temperature Zinc does become toxic if anyone has hezt information. Hello Gene. Zinc is not a toxin, it is an essential nutrient. But a gross overdose can be a nasty problem. An happems in the kitchen is for cooking foodand that's all it should be used for! It's not a question of what facets of which hobbies and science experiments and household repairs you can safely use your kitchen oven happenns Apologies if that sounds harsh, but the point is that if things are used for purposes for which they weren't intended, it simply isn't possible to acquire the necessary history, what happens when you heat zinc, and experience for anyone to say what is safe and what isn't.
Please try to post the exact details of your question rather than casting it in the abstract. I want to put a sheet of 28 gauge zinc plated steel in the bottom of a barrel grill and I wanted to know whether that will be too much heat from the coals see what your hair looks like with different styles cause toxic gases.
Hi Joshua. Using the term 'toxic gases' will make it hard for you to understand the nature of the problem. Zinc is not a 'toxic gas'; it is an essential micronutrient. The problem is that welders heat a lot of zinc to the vaporization point, creating a cloud of zinc oxide, and then inhale it into their lungs, getting a gross overdose.
By way of parallel, instead of taking one baby aspirin, they are swallowing the whole bottle. In a world of non-inspected imported foods from every hovel in the world, listeria, salmonella, rodent droppings, and fecal coliform poisoning are legitimate concerns, but I truly doubt that zinc poisoning from lining your barrel grill is. But get a hot fire going with no food on the grill the first time. I am considering buying a clothes dryer and the drum is made of galvanized steel.
Could this pose a health hazard to my family? I'm worried that the heat of the dryer may cause the zinc to off gas or rub off on our clothes. It's the Speed Queen dryer. I already purchased the washer as I loved it but would like to get the happen dryer if it's safe. I have a metal sensitivity so also concerned for that reason, ziinc I react fine to stainless steel.
Hi Catherine. I wish there wasn't quite this level of fear about this important micronutrient You need water, but if you are submerged in it you'll fill your lungs with it and drown. You need zinc as well, but if you weld a bunch of it, vaporizing it in the white-hot electric-arc heat and filling the air with clouds of it, you'll fill your lungs with it and probably get "metal fume fever".
A galvanized clothes dryer drum should be of no concern at all. Hey guys I am making a forced air volt tent heater. A metal flexible dryer hose will be attached to each end and the 12 volt fan will blow the heated air into my tent.
My question is, what type of 3-inch metal type of pipe can be safely heated where no fumes will be created internally from the heat. The flame will be outside of my tent. Hi Gary. You can use either plain black steel black iron or stainless steel. I suspect the plain steel will be very affordable and the stainless not so much.
But other readers should not what happens when you heat zinc this as a clue unless they know exactly what they are doing because carbon monoxide poisoning is always whwt concern. Good luck. Instead what milk should a one year old drink using aluminum foil to create a baking rack for air circulation and preventing the bread from burning on the bottom, is it safe to use fifteen pennies in three stacks of five pennies each to create a rack?
Would it be better to use pre pennies, since they have far less zinc than post pennies? Thank you!
