What is the process of a solid to a gas called?

The process is called sublimation.Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. Sublimation is an endothermic phase transition that occurs at temperatures and pressures below a substance's triple point in its phase diagram.
  • What happens to the arrangement of water molecules as ice melts?

    The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements.
  • What is it called when a solid changes to a gas?

    It's a process called sublimation. The easiest example of sublimation might be dry ice. Dry ice is solid carbon dioxide (CO2). Amazingly, when you leave dry ice out in a room, it just turns into a gas. Deposition occurs when a gas becomes a solid without going through the liquid state of matter.
  • Why is a solid more dense than gas?

    The atoms or molecules in a solid have fixed positions; they don't move around like atoms or molecules in a gas or liquid do. That's why liquids and gases can flow, but solids don't. Solids are usually much more dense than liquids and gases, but not always.
