Lose
Yes, when a substance freezes, its thermal energy decreases since the molecules lose kinetic energy and slow down as they transition from a liquid to a solid state.
Freezing typically represents a loss of energy. When a substance freezes, its molecules lose kinetic energy and slow down, leading to the formation of a solid structure. This process releases energy in the form of heat.
The freezing point of a substance is lower than its melting point because freezing involves the removal of thermal energy to transition from liquid to solid, while melting requires adding thermal energy to transition from solid to liquid. The freezing point is where the substance goes from a higher energy state (liquid) to a lower energy state (solid).
A substance gains thermal energy when it absorbs heat from its surroundings. This can happen through various processes, such as conduction, convection, or radiation. The thermal energy causes the particles in the substance to move faster, increasing its temperature.
When a substance freezes, its thermal energy decreases. This is because the molecules within the substance slow down and move closer together as they form a solid structure.

During evaporation, a substance gains energy from its surroundings to break the intermolecular bonds and escape as a gas. This results in a cooling effect on the surroundings as energy is absorbed by the substance.
A substance loses energy during cooling and evaporation processes. During cooling, heat is transferred away from the substance, lowering its temperature. During evaporation, the substance loses energy as molecules escape from its surface, causing it to undergo a phase change from liquid to gas.
When a substance freezes, its thermal energy decreases. This is because the molecules within the substance slow down and move closer together as they form a solid structure.
Stoichiometry can be used to determine the amount of heat energy released during the freezing of a liquid by relating the quantity of the substance that freezes to the heat of fusion of the substance. This involves multiplying the mass of the liquid that freezes by the heat of fusion value to calculate the total energy released. This calculation helps in understanding the energy changes that occur during phase transitions like freezing.
The heat of fusion is the amount of energy needed to change a substance from a liquid to a solid. To calculate the energy released when a mass of liquid freezes, you would use the equation Q = m * Hf, where Q is the energy released, m is the mass of the substance, and Hf is the heat of fusion.
As a substance freezes, the particles slow down and come closer together, forming a more ordered and structured arrangement. This transition from liquid to solid is accompanied by a release of heat energy as the particles lose kinetic energy and settle into a fixed position.
