Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.
Wax has a lower melting point than boiling water, so when placed in boiling water, the heat from the water causes the wax to melt. The molecules in the wax absorb the heat energy from the water, which ultimately leads to the wax melting.
The temperature stays the same during boiling and melting because the heat energy is being used to break intermolecular forces rather than raise the temperature. During boiling, this energy is used to convert the liquid into vapor, while during melting, it is used to convert the solid into a liquid.
Boiling takes longer than melting because it requires more energy to break the intermolecular bonds in a substance and convert it from a liquid to a gas. In contrast, melting only requires enough energy to weaken the forces that hold the molecules together in a solid. The process of boiling involves the entire substance reaching its boiling point, whereas melting can occur at specific points within the substance.
Electrovalent compounds have high melting and boiling points because they have strong electrostatic forces of attraction between the positively charged metal ions and negatively charged non-metal ions. These forces require a significant amount of energy to overcome, resulting in high melting and boiling points for these compounds.

Particles of matter absorb energy during melting and vaporization processes, as these transitions involve the breaking of intermolecular forces that hold the particles together. During freezing and condensation processes, particles release energy as they form stronger bonds and lower their energy levels to create a more stable state.
No boiling is heating and energy is added and melting the solid turns into a liquid.
Melting requires energy input or absorption because liquid water has more energy than solid water.
thetons absorb the excess heat
They are both phase changes, this means that until the melting or boiling are complete the temperature of the system remains at the melting or boiling point, despite the continued input of heat energy.
Energy is required in the melting process because high is needed to melt something
condensation and melting
Temperature: Melting occurs at a specific temperature known as the melting point, while boiling occurs at the boiling point. Phase change: Melting involves solid turning into liquid, while boiling involves liquid turning into gas. Energy input: Melting requires energy to break intermolecular forces within the solid structure, while boiling requires energy to overcome intermolecular forces that hold the liquid together. End result: Melting results in a liquid, while boiling results in a gas. External pressure: Boiling point changes with external pressure, while melting point remains constant.
IMF (intermolecular forces) affect the boiling and melting points of a substance by influencing the strength of the bonds between molecules. Stronger IMFs lead to higher boiling and melting points because more energy is required to overcome these forces. Weaker IMFs result in lower boiling and melting points as less energy is needed to break the intermolecular interactions.
