____________ is a physical change from the solid state directly into the gaseous state.
No. Sublimation requires that the solid change from solid to gas without undergoing a chemical change. Eg, dry ice consists of solid carbon dioxide, which sublimes into carbon dioxide gas. Burning is a chemical reaction. A physical change is any change NOT involving a change in the substance's chemical identity. (1) any phase change. Moving between solid, liquid and gas involves only the amount of energy in the sample (this amount is the subject of future lessons). There is no effect on the chemical identity of the substance. Look into phase diagrams. It's not as simple as a specific substance always changing directly from solid to gas, and vice versa. It depends on pressure also. For example, water can change directly from gas to solid at low enough pressure. The term sublimation refers to a physical change of state and is not used to describe transformation of a solid to a gas in a chemical reaction. For example, the dissociation on heating of solid ammonium chloride into hydrogen chloride and ammonia is not sublimation but a chemical reaction. State the term that applies to each of the following changes of physical state: (a) Snow changes from a solid to a liquid. (b) Gasoline changes from a liquid to a gas. (c) Dry ice changes from a solid to a gas. Answers: (a) condensing; (b) freezing; (c) deposition. Practice Exercise. State the term that applies to each of the. following changes of physical state: (a) A refrigerant changes from a gas to a liquid. What is it called when a solid changes state directly to a gas? When a solid changes physical state directly to a gas, we call this change sublimation. Solid carbon dioxide (dry ice) will sublimate directly into a gas (carbon dioxide). T…o learn more about sublimation, use the link below. solid->gas = sublimation    gas->liquid = condensation    gas->solid = deposition Sublimation is when a solid turns into a gas, without becoming a form of liquid first. A physical change is any change NOT involving a change in the substance's chemical identity. Here are some examples: (1) any phase change. Moving between solid, liquid and gas involves only the amount of energy in the sample (this amount is the subject of future lessons). Dye sublimation is defined as the process of solid dye particles changing into gas using heat and pressure, then bond with any polymers (Polyester) present, and change back into a solid. Using these inks and a special ink-jet transfer paper, we are able to create sublimation transfers. I'm sure I remember my dad telling me when I was younger, he was a chemist. Sublimation is the process of going directly from solid to gas. Desublimation, or deposition, is the process of going directly from gas to solid. There are multiple substances that can do this. Sublimation is the phase transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. Sublimation is an endothermic process that occurs at temperatures and pressures below a substance's triple point in its phase diagram.
