How can melted ice be colder than an ice cube
WebThis is the reason why the ice can be returned to its original state. Once it melts due to heat, it becomes liquid water again. 6. give 5 examples of freezing to melting Answer: Water turning into ice when the temperature drops below 0˚C is an example of freezing. Liquid lava turning into solid rock when it cools is called solidifying.
