The name of the process in which a solid changes directly into a gas is called sublimation.
When water vapor changes directly into ice without becoming a liquid first, it forms a process known as deposition. This occurs when the water vapor undergoes a phase transition from a gas to a solid, bypassing the liquid phase.
Sublimation is the phase change in which a substance changes from a solid directly to a gas or vapor without passing through the liquid phase. This process occurs when the substance's vapor pressure exceeds that of its solid form at a particular temperature.
Sublimation is the phase change that changes a solid directly to a gas or vapor without first changing to a liquid. In this process, the solid particles gain enough energy to break free from the solid structure and enter the gas phase without passing through the liquid phase.
No, condensing is the turning of water gas (vapor of steam) into a liquid while solidification is changing the liquid phase into a solid phase (ice). I believe if I can remember my Thermdynamics that all fluids can also directly from gas into a solid at high pressures. I believe that is called sublimation.
The process by which water vapor changes directly to a solid is called deposition. During deposition, water vapor skips the liquid phase and turns directly into ice or frost on a surface.

The name of the process in which a solid changes directly into a gas is called sublimation.
The process by which water vapor changes to a solid is called deposition. This occurs when water vapor in the air changes directly into ice without passing through the liquid phase. This can happen when the temperature and pressure are low enough for the water vapor to bypass the liquid phase and form ice crystals.
Water vapor that changes in to an ice crystal is called deposition. This what happens in the formation of snow.

Sublimation is the process when a solid changes directly into a gas without first becoming a liquid. This occurs when the conditions are such that the solid phase can bypass the liquid phase and enter the gas phase.
The process of water vapor turning directly into ice crystals is called deposition. This occurs when water vapor in the air changes directly into solid ice without first becoming a liquid. This process is often seen in the formation of frost or snowflakes.
Snow forms when water vapor changes directly into a solid without first going through the liquid state. This process is known as deposition.
Solid changing directly to a gas is called sublimation. In this process, the solid skips the liquid phase and turns directly into a gas when heated. This occurs when the vapor pressure of the solid exceeds the atmospheric pressure.
Water vapor changes into a solid when it undergoes the process of deposition, where it goes directly from a gas to a solid without becoming a liquid first. This occurs when the water vapor is cooled to its dew point temperature and condenses into tiny ice crystals or frost.
