Solution
The correct options are
A Boiling
B Melting
C Freezing
Boling is a process due to which a liquid changes into a gaseous state at a constant temperature by absorbing heat energy. Melting is a process due to which a solid changes into a liquid at a constant temperature by absorbing heat energy.
Freezing is a process due to which a liquid changes into a solid at a constant temperature by releasing heat energy.
Evaporation is a surface phenomenon, it does not happen over a single temperature range.
