Introduction:
Water exists in three states: solid (ice), liquid (water), and gas (steam). Each state has its own unique properties, including how it interacts with its environment. One such property is the cooling effect of ice and the burning effect of steam.

Ice:
When water freezes and becomes ice, the molecules slow down and become packed together, forming a crystalline structure. This structure allows ice to absorb heat energy from its surroundings, which causes the ice to melt. This is why ice feels cool to the touch. When we apply ice to an injury, it draws heat away from the body, reducing inflammation and pain.

Steam:
When water is heated, it begins to evaporate and turn into steam. Steam is made up of water molecules that are moving at a very high speed and colliding with each other. This results in a lot of energy being stored in the steam. When steam comes into contact with our skin, it transfers this energy to our skin, causing burns.

Conclusion:
In summary, the cooling effect of ice and the burning effect of steam can be explained by the properties of the different states of water. Ice absorbs heat energy from its surroundings, making it feel cool, while steam contains a lot of energy that it transfers to anything it comes into contact with, causing burns. Understanding these properties can help us use water in its different states safely and effectively.
