Why does steam at 100 degrees celsius cause a more severe burn than water at 100 degrees celsius?

In the process of condensing back to a liquid, additional heat of 540 Calories per gram is released by steam, making burns potentially worse. However, the lower density of steam is a factor in the opposite direction. One needs to consider all aspects of the particular heat transfer situation.

THANK YOU SO MUCH DRWLS UR DA BOMB!!!! :)

It's simple, Steam is a concentrated form of water vapor. Since steam has a force to it, it can penetrate the skin faster than water that is 100 degrees. I hope this helps.

Steam at 100 degrees Celsius causes a more severe burn than water at the same temperature because steam contains a significant amount of latent heat. To understand why, we need to delve into the concept of latent heat and the difference between steam and water.

When water is heated, it absorbs energy and undergoes a phase change from a liquid to a gas, which we call steam. This phase change requires a substantial amount of heat energy. This additional energy is known as latent heat, and it is stored within the steam.

Now, when steam comes into contact with our skin or any cool surface, it condenses back into liquid water. During this process, the steam releases its stored latent heat to the surrounding area, typically in the form of an intense burst of heat. This heat transfer is much more rapid and efficient than when water at the same temperature comes into contact with our skin.

In contrast, water at 100 degrees Celsius does not undergo a phase change. When it comes into contact with our skin, it transfers heat more gradually through conduction. The temperature of the water decreases as it gives up its heat to our skin, resulting in a slower and less severe burn compared to steam.

In summary, steam at 100 degrees Celsius causes more severe burns than water at the same temperature due to the additional latent heat it carries, which is rapidly released upon contact with cooler surfaces.
