When a solid gains thermal energy, its atoms and/or molecules begin to move (vibrate) faster and faster as the temperature continues to increase. Eventually, the particles that make up the solid will gain enough thermal energy in order to separate into a liquid through melting or into a gas through sublimation.
In order for a chemical reaction to occur, there must be a certain amount of energy to break, and then reform chemical bonds. The collision of particles must also occur at the correct angle for a chemical reaction to occur. Heat is essentially the energy a substance has, so the higher the temperature, the higher the energy of of the particles. If the particles have a higher energy, they move around faster, therefore increasing the probability of a successful collision. The energy (or velocity) of particles is also higher, therefore creating higher chance that there is enough energy in the chemical collision for the reaction to occur.
the particles in a gas lose enough thermal energy to form a liquid.

A liquid can expand when thermal energy is absorbed which is known as thermal expansion, but the thermal energy is not enough to change the liquid's state. When there is enough thermal energy, the liquid may change to a gas if the particles move fast enough to escape the liquid or it may change to a solid if the thermal energy is released from the matter.
the spoon will increase in thermal energy, and the soup will decrease in thermal energy. Reason: Thermal energy is the total of all the kinetic and potential energy of the atoms in an object. When the thermal energy of a substance increases, its particles move faster. If the thermal energy of a solid increases enough, it melts into a liquid. The liquid state of a substance always has a higher thermal energy than its solid state. If the liquid continues to gain thermal energy, its particles speed up more. When the particles of a liquid have absorbed enough energy to escape the forces between them, the liquid becomes a gas. The substance has undergone another phase change. As the total kinetic energy of the particles in an object increases, the object gets warmer. Heat flows from a warmer object to a cooler one.

A solid melts when it gains enough thermal energy.

Think what happens if you place a glass lid over a pan of boiling water. You will see liquid form on the underside of the lid. Instead of escaping from the closed pan, the water vapor formed from boiling hits the cooler lid and forms liquid drops through condensation. Energy is transferred as heat from gas particles to the lid. The gas particles no longer have enough energy to overcome the attractive forces between them, so they go into the liquid state.
