A substance changes from a solid to a liquid at its boiling point. True or false

Answers

The answer is false
For an ex: an ice is a solid once it's melts cuz of the heat it's a liquid but if u boil the liquid then it's at it's boiling point

Idk I'm not that really good in science sorry......
True because if it gets to its boiling point then it would start to melt then become liquid and then will harden up over time and change back to a solid in a different form
