Why does the temperature of a substance not change when the phase changes?
1.) The energy is going into breaking/forming intermolecular interactions, allowing for phase change
2.) The energy must be converted to another form of radiation before it can increase the temperature
3.) The temperature changes but not enough to be measured
4.) The matter absorbs all the energy into the covalent bonds of the molecule, preventing any temperature change.
