When water is in the form of ice, it has a lower temperature than the surrounding environment. When it comes into contact with something warmer, such as our skin, it absorbs heat from it in order to melt, causing a cooling effect. This is why ice is commonly used to reduce swelling and inflammation in injuries.
On the other hand, when water is in the form of steam, it has a much higher temperature than the surrounding environment. When it comes into contact with our skin, it transfers its heat to our skin, causing burns. The high temperature of steam can cause damage to our skin and tissues, leading to severe burns.
In both cases, the temperature difference between the water and its surroundings is what causes the cooling effect or burns.

Water as Ice Has a Cooling Effect
- Ice is at a lower temperature than the surrounding environment.
- When ice comes into contact with a warmer surface (e.g., skin), heat flows from the surface to the ice, causing the surface to cool down.
- This heat transfer process absorbs energy from the surface, resulting in a cooling sensation.
Water as Steam May Cause Severe Burns
- Steam is water in its gaseous state and can exist at a much higher temperature than liquid water.
- When steam comes into contact with skin, it condenses to liquid form, releasing large amounts of heat (latent heat of vaporization).
- This sudden release of heat causes a rapid increase in skin temperature, which can result in severe burns.
- Additionally, steam can penetrate deeper into the skin than liquid water, causing more extensive tissue damage.
Summary
The difference in cooling effects is due to:
- Temperature difference: Ice is colder than the skin, while steam is much hotter.
- Heat transfer: Ice absorbs heat from the skin, while steam releases heat to the skin.
- Latent heat release: Steam releases a significant amount of heat when it condenses, which contributes to the burning effect.
