Solution

Water turns into ice when temperature decreases to 0 degrees C. Water turn into steam at 100 degrees C when heat is supplied to water. Water as steam has more latent heat while water as the liquid does not. Hence water as steam may cause severe burns while water as ice has a cooling effect.
