Stoichiometry can be used to calculate the energy released during the melting of a solid by determining the amount of heat required to convert the solid to a liquid. This conversion involves breaking intermolecular forces but does not change the chemical composition. The energy required can be calculated using the heat of fusion, which represents the amount of energy needed to melt one mole of a substance at its melting point.
Stoichiometry can be used to calculate the energy absorbed when a mass melts by considering the enthalpy of fusion, which is the amount of energy required to change a substance from solid to liquid at its melting point. By using the molar mass of the substance and the enthalpy of fusion, you can calculate the amount of energy needed to melt a specific mass of the substance.
Stoichiometry can be used to calculate the energy absorbed when a mass of a solid melts by considering the heat energy required to overcome the intermolecular forces holding the solid together. By using the heat capacity of the solid, the mass of the solid, and the enthalpy of fusion for the substance, stoichiometry can help determine the amount of energy needed for the solid to melt.
Energy is absorbed when ice melts because the process of melting requires breaking the intermolecular forces holding the water molecules in a solid state. This breaking of bonds requires energy input, known as the heat of fusion. This energy is used to overcome the attractive forces between the water molecules, allowing them to move more freely and transition from a solid to a liquid state.
It is false that an ice cube melts when it's mechanical energy increases.
A change in temperature affects the melting of ice by either speeding up or slowing down the process. When the temperature increases, the ice absorbs heat energy and melts faster. Conversely, when the temperature decreases, the ice absorbs less heat energy and melts slower.

No. When a substance melts it absorbs energy.
released
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.

When a fuse wire melts, the electrical energy is transferred as heat energy and light energy.
When water molecules melt, energy is absorbed. When water molecules evaporate, energy is also absorbed. When water molecules condense energy is released. When water molecules freeze energy is also released.
heat
When matter melts, the energy is used to break the bonds holding the solid structure together, causing the particles to move more freely. This increase in energy leads to a change in state from solid to liquid, without any increase in temperature. The energy required for melting is known as the heat of fusion.
The thermal energy of the water increases as it melts, changing from a solid (ice) to liquid water. For a solid to melt, it is necessary for it to absorb energy from its surroundings.
