Generally, melting is the process of turning from a solid to a liquid. It entails gaining energy.
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
During a change of state, such as melting or boiling, the particles in a substance rearrange their positions and gain or lose energy to move from one state to another. For example, in melting, solid particles gain enough energy to break their fixed positions and move more freely, turning into a liquid. Conversely, in boiling, liquid particles gain enough energy to break free from each other and turn into a gas.
The process of melting requires energy input, so it is a gain of thermal energy. This is because the energy is needed to overcome the intermolecular forces holding the solid together and to increase the kinetic energy of the molecules in order to transition from a solid to a liquid state.
The energy transformation involved in melting snow is typically a change from heat energy to kinetic energy. When heat is applied to snow, it absorbs the energy and the snow particles begin to gain energy and move more quickly, resulting in the melting of the snow.
The changes of state characterized by having atoms that gain energy are melting and vaporization. In melting, solid atoms gain enough energy to break the bonds holding them in a fixed position, transitioning to a liquid state. In vaporization, liquid atoms gain sufficient energy to overcome intermolecular forces, transitioning to a gaseous state.
A material must gain energy both before and during melting.

Lose
Most substances lose or gain energy when their temperature changes.
a closed system will not gain or lose mass
When condensation occurs, it is a gain thermal energy.

The energy that causes a change of state in a system is typically thermal energy. When thermal energy is added or removed from a system, it can cause the particles within the system to gain or lose kinetic energy, leading to a change in the state of matter (such as melting, freezing, boiling, or condensation).
