What is the difference between water and ice?
Ice is cold, hard water, in solid form. Both water and ice consist of hydrogen and oxygen molecules. In general, pure water at sea level is in liquid form when its temperature is greater than 0 degrees Celsius (32 degrees Fahrenheit) and in solid form (ice) when its temperature drops below 0 degrees Celsius (32 degrees Fahrenheit). It turns to a gas, water vapor, when its temperature rises above 100 degrees Celsius (212 degrees Fahrenheit).
