It involves a loss of thermal energy.
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
The path of thermal energy in a refrigerator is that the thermal energy is removed from the gas, it condenses, or become liquid.
Iron naturally exists in solid state and heat is required for its liquifaction so liquid iron has high thermal energy.
Its temperature declines, and it may change phase ... from liquid to solid, or from gas to either liquid or solid.
You can change both of these by increasing or decreasing the speed of the molecules (kinetic energy), or by increasing or decreasing the heat applied (thermal energy). If you want to melt ice, you can increase the kinetic energy by increasing the thermal energy. The opposite occurs if you want to freeze water.
To become a solid, a liquid will absorb heat energy.
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.
An increase in thermal energy may change a solid to a liquid, a liquid to a gas, or a solid to a gas.A decrease in thermal energy may cause a change in the opposite direction - for example, from a liquid to a solid.

Yes because when the thermal energy of a substance increases, it's particles move faster. If the thermal energy of a solid increases, it's particles melts into a liquid. The liquid state of a substance always has a higher thermal energy than it's solid state

A gas has more heat energy, often called thermal energy, than a liquid, even if both the liquid and gas are at the same temperature. Consider that the gas molecules have more thermal energy than liquid molecules of that same substance. The gas molecules are "free" to move around more because they have more kinetic energy than molecules of the liquid. And kinetic energy is function of thermal energy. If we consider the case of water molecules to illustrate our point, when a pan of water is boiling, the water molecules escaping the pan as a gas have more kinetic energy than the ones making up the liquid water that is still in the pan. Also consider the case of water that is evaporating. Wet your finger and blow on it. The liquid water on your finger cools as the evaporating water molecules take thermal energy from that liquid to make their change of state possible. It takes an increase of thermal (heat) energy to change a liquid into a gas.
When a sample of liquid is cooled its thermal energy goes to its surroundings
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.
