Steam

Could someone reiterate why steam causes more severe burns? How does the energy relate to this?

More energy is required to turn water into steam, so when it comes into contact with skin, it transfers a greater amount of heat energy.

Even though the temperature of the system doesn't increase in the vaporizing transition state, heat is still increasing as energy is applied to the system. So, when the steam comes in contact with your skin and condenses, all of the energy stored in the bonds gets transferred to your skin and the water is still at 100˚. So, the steam is transferring more heat for a longer period of time, leading to more severe burns.

steam has "stored" energy in its molecules as they move freely;
when steam condenses upon contact with skin, it release said energy because of the difference in temperatures

simply put, steam can cause severe burns due to its high heat energy

Steam causes more severe burns because it has more heat energy since there is a phase change from liquid to gas.

During a phase change, temperature does not increase. The energy goes into breaking bonds.
