Title says all. How does vapor from e-cigs not burn you when steam from boiling water can cause blistering?
In: Physics
It’s apparently pretty [complex chemistry](https://www.reddit.com/r/askscience/comments/2l8e7k/comment/clsi9ej). Steam is high temperature water to the point it has become a gas, while vapor is at a lower temp and is still in the form of water droplets floating in the air.
