Every substance melts at 0 degrees celsius and boils at 100 degrees celsius. true false

False, that only applies to water as far as I know, but I know for a fact that gold does not melt at 0 degrees Celsius

Hello! It is true that water boils at 100% C, however, this is not true for any substance. Take steel, for instance, steel would take MUCH higher temperatures to melt, and to boil. As it says "ANY SUBSTANCE" this would be false.

I hope this helped!

I am, yours most sincerely,
