# The change of matter from the solid state to the gaseous state is called direct

The transition of matter from the solid state to the gaseous state is called direct. We often hear this term in science and physics classes. This is also a phenomenon that we always notice in one of our daily details. Therefore, it is necessary to identify them and understand the mechanism of their occurrence, and here we are, in our next article, we will explain this by explaining the different states of matter and their transitions.

## What is the direct transition of matter from a solid to a gaseous state called?

Matter is everything that occupies a space of space. Matter exists in nature in three states, which are the solid state, the gaseous state, and the liquid state, where each state has characteristics that differ from others. The matter can be converted from one state to another in different ways, such as melting, evaporation, and freezing, where the transition of matter from a solid state to a solid state is called Gaseous state directly is an important physics term that refers to one way of transition between phases of matter. correct answer

• The transition of matter directly from the solid state to the gaseous state is called sublimation.

Sublimation is a unique type of direct transition between phases of matter, which involves the transition of matter from a solid to a gas directly, bypassing a liquid state, a typical example of this process being the direct transition from ice. in water vapor on very cold winter days.

## State the reasons for the transition of matter from the solid state directly to the gaseous state

The state of the material moves from one stage to another under the influence of a measure of thermal energy or pressure, where the heat causes a high kinetic energy, which leads to the displacement of the particles of the material from each other in a way that guarantees a change in their state, and this energy also affects the electrons surrounding the atoms, which leads to chemically breaking their bonds, causing solids to turn into a liquid, then into a gas, and then into a plasma or other additional states, while the lower temperature changes the previous course; Convert gas to liquid etc. We must also not forget the effect of pressure, which plays a role in the transition between the different phases of matter, since the molecules of matter tend to assume the most stable state, sometimes causing the process of mixing heat and pressure from transition states. states to override. This means, for example, that a solid body goes directly into the gaseous state, bypassing the liquid state.

## What are the methods of transition between states of matter?

The physical states of matter are divided into three types: solid, gaseous, and liquid, but the transition between these states often occurs through reflexive physical processes that do not involve chemical changes in the structure of matter. These changes, note the following

• Freezing The process by which a substance changes from a liquid to a solid state.
• Fusion is the process of changing a substance from a solid to a liquid state.
• Condensation is the process by which a substance changes from a gaseous state to a liquid state.
• Evaporation is the process of changing matter from a liquid to a gaseous state.

Therefore, we have come to the end of our article entitled Transition of a substance directly from the solid state to the gaseous state, where we got acquainted with the term sublimation and the reasons for its occurrence, in addition to clarifying the most famous cases of transition between the phases of matter.
