Steam burns

Postby Clarice Chui 2C » Sun Feb 02, 2020 9:57 pm

Why, conceptually, does steam cause severe burns?

Steam has more energy than boiling water does (40.7 kJ vs 5 kJ). So when the steam hits your skin you are immediately feeling 40.5 KJ of heat rather than 5KJ. Steam also absorbs heat so it will also increase in temperature.

It is because of latent heat of vaporization, so steam has a lot more heat energy, so much it makes more severe burns than boiling water does.

Steam releases more energy as opposed to boiling water, the steam releases about 40 kJ of energy.

If you look at a phase change graph, you will see that the change between liquid and gas is represented by a straight line in which heat is increasing but the substance has not yet changed phases. Therefore, steam holds a greater temperature.

steam has more energy than boiling water at the same temp

Because of the energy to convert boiling water to steam is a lot. So when steam condenses on your skin, all the energy expelled to form the bonds between water will get sent to your skin causing extreme burns.

Since steam releases a lot more energy in comparison to regular boiling water, the burn that the steam inflicts is much more severe than that of the boiling water.
