heat increases kinetic energy i.e. motion of the particles leading to bond breakage which ultimately causes phase change
in my opinion, I don't really know
If the molecules in question have a solid phase, for example water which goes from liquid to solid, namely ice, then least kinetic energy is the solid phase, with minimum kinetic occurring at 0 Kelvin (absolute zero).
Water has the highest kinetic energy in the liquid phase, as the molecules are moving freely and have enough energy to flow and take the shape of their container.
Kinetic energy is the energy of motion, and it plays a crucial role in the behavior of atoms and molecules. Atoms and molecules are constantly in motion due to their kinetic energy, which affects their interactions with each other. This motion determines properties such as temperature, pressure, and phase changes in matter.
A thermometer measures temperature by detecting the average kinetic energy of the particles in a substance, rather than the energy involved in phase changes, such as latent heat. Latent heat is the energy absorbed or released during a phase change, like melting or boiling, and does not directly affect the average kinetic energy of the particles that the thermometer detects.
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.

A heating curve shows the relationship between temperature and heat added to a substance. During phase changes, the temperature remains constant as the added heat is used to break intermolecular forces. Kinetic energy increases with temperature, so during phase changes, the added heat is used to increase potential energy (for breaking intermolecular forces) rather than increasing kinetic energy (temperature).
When heat is added to a pure phase of matter, the kinetic energy of the particles in that phase increases. This increase in kinetic energy causes the particles to move faster and the temperature of the phase to rise.
Particles have the most energy in the gas phase, where they have high kinetic energy and are further apart. In contrast, particles have the least energy in the solid phase, where they have the least freedom of movement and are held together in a fixed structure.
Average kinetic energy on an atomic or molecular scale is what we perceive as temperature, and temperature is a major determinant of phase (along with pressure, which is the other major determinant).

This is the solid phase.
