The molecules of the substance gain thermal energy as a result of which they vibrate more energetically. When the molecules have acquired enough energy they escape from the solid and enter the gaseous phase. Incidentally, there is no requirement for there to be a liquid phase between the solid and gas.
The thermal energy of a substance increases when it changes from a solid state to a liquid state, or from a liquid state to a gas state. This is because the molecules in the substance gain more kinetic energy and move more freely as the substance transitions between states of matter.
A physical change involves a transformation in the appearance, shape, or state of a substance, while its chemical composition remains the same. This means that no new substances are formed during a physical change.
The negative value of latent heat in a substance indicates that energy is being released when the substance changes its state, such as from a gas to a liquid or from a liquid to a solid. This release of energy is important because it affects the temperature and behavior of the substance during these phase changes.
When a substance changes from one state of matter to another (e.g. solid to liquid, liquid to gas), the arrangement and movement of its particles are altered. Energy is either absorbed or released during the change, causing the substance's temperature to either increase or decrease. This process is known as a phase transition.
Energy can change when a substance undergoes a phase change (such as melting or vaporization) or a chemical reaction. During these processes, energy is either absorbed (endothermic) or released (exothermic) as the internal structure of the substance changes. This energy change is due to the breaking or forming of bonds between atoms, resulting in a change in the overall energy content of the system.
It can melt into a liquid, it can be juiced,

When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
The substance that changes is the hydrogen peroxide. After it reacts, it forms bubbles of oxygen and water.

The temperature remain constant during a change of phase.
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.
Vaporation takes place when the particles in a liquid gain enough energy to move independently forming a gas. if anyone has more info please add it. Thank you
When a substance changes from a solid to a liquid and vice versa, its density changes.
The overall mass of a substance remains the same when it changes state. The mass is conserved during physical changes like melting, freezing, vaporization, or condensation. This is because the number of atoms or molecules in the substance does not change during a change in state.
During a physical change, the characteristics of a substance such as size, shape, and phase may change, but its chemical composition remains the same. These changes are reversible and do not result in the formation of a new substance.
