It is false that an ice cube melts when it's mechanical energy increases.
The temperature of ice increases when it melts.
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.
both. It depends what substance it is. For example: solid water (ice) melts into liquid water (water) and then that melts into gas water (water vapour). Another example is that frozen carbon dioxide (c02)which is a solid also known as dry ice, melts into c02 gas hence the name dry ice because when it melts it goes straight into a gas state.
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.

An ice cube will melt when it is above the freezing point of water. At this point the individual molecules have enough energy to vibrate more causing the ice cube to melt.
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.

Their speed - Kinetic Energy - increases as the solid melts.

it decreases.
When ice melts due to friction, energy is converted from mechanical energy into thermal energy. Friction between the ice and another surface generates heat, causing the ice to melt and absorb energy in the process.
Ghee melts on heating because when ghee is cold it is solid and the kinetic energy is less so the particles are situated closer and when heated the particles of matter spread and the interrmollecular force increases as the intermollecular force is more in liquids the ghee changes to liquid or melts.
When the temperature increases ice melts because as the heat increases the water particles start to move faster and faster as they have more and more energy. This is also known as melting point.
Adding heat will do one of the following, or both: * The temperature of the substance increases. The individual particles move faster; their kinetic energy increases. * The substance changes its state (for example, when ice melts, it changes from solid to liquid). The potential energy of the particles increases.
