explain this include the straight line , curve line etc.

How does the temperature of a solid change when it melts? solid liquid gas Boiling point of without a temperature increase. water: At O C, more heat is added Heating of solid ice makes 100 C its temperature rise. At 100"C, more heat is added No phase transitions Temperature to liquid water, but it's temperature after 100 C. More does not rise. heat leads to a higher temperature. Melting point of ice: 0. C makes its temperature rise Heating of liquid water Heat added
