The formation of a double bond (the sharing of two electron pairs) between each oxygen and the carbon would result in each of the three atoms achieving a full valence shell. As the ice melts from heat coming from the water, it will remain at 32 degrees Fahrenheit (0 degrees Celsius) until the entire ice cube melts before continuing to warm.
