The phase change from gas to solid is called deposition.
For example, at 5 times normal air pressure, liquid carbon dioxide would form around -56°C (-70 °F). But at normal pressure, the liquid is unstable and tends to remain a gas. Cooling the gas further to -78.5 °C (-109.3 °F) will form solid dry ice.
What else can I help you with?
What is the physical change of carbon dioxide and snow disappears?
The physical change that is happening is called sublimation. Sublimation is when a solid (snow) directly turns into a gas (carbon dioxide) without passing through the liquid state.
Is melting snow a physical change or chemical change?
Snow disappearing is a physical change. It is a combination of melting and then evaporating and of sublimation.
Is subliming ice a chemical change?
No, subliming ice is a physical change where ice changes from a solid directly into a gas without melting into a liquid first. It is a phase transition process and does not involve any chemical reactions or changes in the chemical composition of the ice.
Is it true melting is considered an sublimation change because energy is gained by substance as it changes stae?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Sublimation is a phase change in which a solid moves directly into the gas phase. Both melting and sublimation are two types of physical change.
What is the oppersit of sublimation?
A phase change from gas directly to solid is called deposition.
What kind of process is sublimation?
Sublimation is a physical change of state, from solid directly to gas.
What is the sublimation of carbon dioxide a chemical property or chemical change?
The sublimation of carbon dioxide is a physical change, not a chemical property or change. Sublimation is the process in which a substance transitions directly from a solid to a gas without going through the liquid phase, and it does not involve any change in the chemical composition of the substance.
Is sublimation of mothballs physical or chemical change?
Sublimation of mothballs is a physical change. Sublimation is the process of a substance transitioning from a solid directly to a gas without going through a liquid phase. It does not involve a change in the chemical makeup of the substance.
What is the physical change of carbon dioxide and snow disappears?
The physical change that is happening is called sublimation. Sublimation is when a solid (snow) directly turns into a gas (carbon dioxide) without passing through the liquid state.
Is sublime a physical change or chemical change?
Sublime is a physical change because it involves a substance changing from a solid directly to a gas without going through a liquid phase. This process is reversible, and the chemical composition of the substance remains the same.
Is solid iodine sublimes into purple vapor a physical or chemical change?
Sublimation of solid iodine into purple vapor is a physical change because the chemical composition of iodine remains the same throughout the process. Only the physical state changes from solid to gas.
Is melting snow a physical change or chemical change?
Snow disappearing is a physical change. It is a combination of melting and then evaporating and of sublimation.
Is subliming ice a chemical change?
No, subliming ice is a physical change where ice changes from a solid directly into a gas without melting into a liquid first. It is a phase transition process and does not involve any chemical reactions or changes in the chemical composition of the ice.
What is the opposite of sublimation?
The opposite of sublimation is deposition, which is the process of a gas directly becoming a solid without going through the liquid state.
What is the the opposite of sublimation?
The opposite of sublimation is deposition, which is the process of a gas directly becoming a solid without going through the liquid state.
What are three physical changes?
when a physical change happens the substance is not chemically change only its state of matter has changedMelting, Freezing, Deposition, Sublimation, Condensationand Evaporation
Is burning woo sublimation?
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
