which burn is the worse a boiled water or steam both at same temp 100 degree celisus?

Question

i need this is this general and critical any ideas and please enter why if u pick steam ???? thanks

Answer 1

Its hard to say under these condition without know an exact pressure or time of exposure to the substance. What you need to know is that burning is a result of heat exchange over a period of time. If you can decapitate the heat through your body's natural cooling system, then it won't burn. You can pass your hand slowly over the steam coming off a pot and you won't burn. But if you put your hand in the boiling water for the same length of time then your hand will be burned. That's because the water being much more dense than the steam will have greater contact with your hand and the heat transfer will be much much greater. More than your hand can handle. So it will burn.
The thing with steam is that, under pressure, it can build up a lot of heat. actually steam actually contains more heat per gram of substance than of water. even up into the 200 to 250 degrees or more. At this temperature and pressure, it can rip your flesh off the bone on contact. While water can on affect the top two layers of your skin the "epidermis" and the "dermis" Burning through conduction or convection is always based on rate of heat transfer over time .
Think of a sauna with100 degree steam around you. Your body is able to cool itself for a period of time. But just touching the water that's boiling will burn you.

Answer 2

Steam. Even though they are both at the same temperature, the steam has more energy. The greater the energy, the nastier the burn. The difference in energy is called "The Latent Heat of Vapourisation".
Latent is another word for hidden, it's a latent heat because the temperature reading alone doesn't show that steam and water at a 100 degrees have different energies.
This extra energy is needed to allow water at a 100 degrees to become a gas, in the liquid state water has attractions between it's molecules, when the molecules are provided with enough energy to overcome these attractions the water turns into steam.
So when you get burned by steam it's like being burned with water plus the extra (latent) heat of the steam as it hits your arm or whatever and condenses to water again.
Hope this helps.

Answer 3

Steam. The steam will first burn by giving away heat (latent heat of condensation) and become boiling water. Then after the two are equal.

The latent heat of steam is 540 times more than specific heat of water.

Say, 1 gram of boiling water gives heat equal to 1 x 1 x (100 -37) = 63 calories of heat (in CGS system )

1 gram of steam will give 540 + 63 calories of heat.

Steam is far more dangerous.

Answer 4

Well as you may or may not know, at 100 degrees Celsius, it considered boiling temperature in Standard thermometer Fahrenheit readings, 212 degrees. A steam burn is much worse than a scald burn. A water scald burn will burn only the top two layers of tissue, called the epidermis and the dermis. More deeper subcutaneous tissue will not be harmed. This is of a typical scald burn, like water on the stove or something.
Steam on the other hand is far worse. Steam is ionized water, vaporized into tiny water particles that retain heat much more so than regular water. The burn from steam can burn far worse than water, due to the tissue depth that is burned. It is almost to the point of a flame burn. The epidermis, dermis, subcutaneous tissues, and even in some areas of the body, muscle tissue and nerve clusters can be totally destroyed.

Answer 5

The steam burn will be worse, because in addition to the heat contained in the water at 100°C, there is the latent heat of vaporization that is released when the steam condenses to water on your skin.

Had that same question in high school chemistry.

Answer 6

nicely it incredibly is steam because of the fact think of approximately steam is the 0.33 state of water or remember sturdy liquid gas. gas or steam is warmer then liquid it incredibly is the warmth of evaporation. think of approximately it you pour boiling water on you it burn. Steam is approximately 10 x warmer and covers a hudge area reason it spreds out .

Answer 7

steam! At the same temperature, it contains more heat compared to water.

heat of steam = heat of water + mass of water * 540

Answer 8

because the temp is the same, the other variable involved in the burning are: time of exposure and surface contact, and heat capacity.
Heat capacity of water is much higher than heat capacity of steam.
In Finland is not unusual to do a sauna at 90°C, but you will burn yourself even at 50°C with water.

So in my opinion boiling water at 100°C is much worse.

Answer 9

they are equal
