Does boiling water gain energy?
Evaporation When water reaches its boiling point of 100ºC, the water molecules move very quickly and are released from the gravitational pull that holds them in the liquid state. … Condensation When vapor is cooled, it releases thermal energy and converts to the liquid state.

Is steam worse than fire?
You may have heard that even though steam and water are technically the same temperature, steam can make burns worse. Why does this happen? The reason is that steam, which burns the skin, also changes phases. It also turns into water.
Does steam or water burn worse?
Steam can cause burns worse than boiling water. This is because steam turns back into a liquid when it touches the skin. When this happens, it releases energy. That energy, along with the heat itself, affects the degree of the burn.
