Adding or removing thermal energy alters the arrangement and movement of particles within a substance, leading to state changes. Imagine tiny dancers representing the particles in a substance.
To put it simply, each particle contributes to the total thermal energy. Therefore, if you have a larger number of particles moving and interacting with each other, the overall energy will increase.
When you add thermal energy to a solid, liquid or a gas, then you are making the particles in that matter move faster as each particle receives more kinetic energy.
In the solid-state atoms and molecules stick together, and as we add thermal energy to a solid state, the temperature of the solid increases, and molecules, and atoms oscillate faster. When we add enough thermal energy, oscillation becomes so high that bonds between molecules or
When you add heat energy to a substance, one of two things can happen: either the temperature of the substance will increase, or the phase (or state) of the substance will change.
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).

For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a gas). When heat is applied to a solid, its particles begin to vibrate faster and move farther apart.
When you add thermal energy to a solid, liquid or a gas, then you are making the particles in that matter move faster as each particle receives more kinetic energy.
When thermal energy is added to a solid, the kinetic energy of the particles in the solid increases, causing them to vibrate more rapidly.
As you add thermal energy, the molecules in the liquid vibrate and move faster, increasing the average kinetic energy and raising the temperature. Expansion: Most liquids expand as they heat up.
Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
What happens if you add heat to a solid it will? If a solid is subjected to heat, it will expand. On reaching its melting point, the solid will become liquid.
The temperature reflects the thermal energy content of the material—the addition of heat increase the vibrational motions, and temperature increases. Ultimately, the solid changes to a liquid and the liquid changes to a gas phase as more heat is added, as illustrated in Figure 1.9.1.

If heat is removed from a substance at its melting point, the reverse of melting, i.e., freezing, happens, i.e., the liquid gradually changes from liquid to solid phase. The energy equal to the heat of fusion is released during the freezing process.
When you add heat to a substance, you are adding energy to the substance. If the heat (energy) is used to change the state of the substance, say by melting it, then the added energy is used to break the bonds between the molecules rather than changing their kinetic energy.

Adding or removing thermal energy alters the arrangement and movement of particles within a substance, leading to state changes. Imagine tiny dancers representing the particles in a substance. Their movements and interactions determine whether the substance is a solid, liquid, or gas. Adding Thermal Energy (Heating):

Adding Thermal Energy (Heating): Increased Particle Movement: When you heat a substance, you add thermal energy, making the particles move faster and vibrate more intensely. This disrupts the forces holding them together, like tiny dancers bumping into each other.
The heat added at the melting point is used to change the particles from a well-arranged form in the solid to an irregular arrangement in the liquid phase. This process is called the melting of solid. The energy needed to melt a unit amount of the substance is the heat of fusion (∆H fus).
Energy makes particles move. The more energy the particles have, the faster they can move and the farther apart they can get What happens inside a solid, liquid, or gas as its temperature goes up? What happens to matter when its temperature decreases? What happens to matter if its temperature continues to rise or fall?
