The heating curve of naphthalene
B C
At point B :
solid naphthalene begins to melt.
During the melting process, the temperature of naphthalene
A does not rise even though heating continues.
The temperature remains constant because the heat energy
absorbed by the particles is used to overcome the forces
between particles so that the solid can turn into a liquid.
At this temperature, both solid and liquid are present.
