What else can I help you with?
Dry ice has the unique physical property called sublimation This means that solid dry ice can?
turn directly into gas....
Is the temperature at which dry ice evaporates a chemical or physical?
The temperature at which dry ice evaporates is a physical property. It is the sublimation point of carbon dioxide, where it changes directly from a solid to a gas without passing through the liquid phase.
What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
Is sublimation of dry ice a change of state?
Yes, sublimation of dry ice is a change of state. It refers to the process where solid carbon dioxide (dry ice) transitions directly to gas without passing through a liquid phase. This occurs when dry ice is exposed to temperatures above its sublimation point, resulting in the release of carbon dioxide gas. Thus, it is considered a physical change in the state of matter.
IF solid dry ice slowly disappears completely is this a physical or chemical change?
The "disappearance" of dry ice is a physical change. What you refer to as disappearance is actually sublimation where the solid CO2 turns to a gas without going through the liquid phase. Dry is is solid CO2 and when it disappears it becomes gaseous CO2, so it is a physical change.
Solid changing into a gas?
sublimation. example dry ice
Is a physical change A. an iron bar rusting B. oil floating on water C. a copper skillet tarnishing D. the sublimation of dry ice?
The answer is D; the sublimation of dry ice. A physical change alters one of the physical properties of a substance (e.g. size, shape, color, etc.), but it does not change the substance itself. A chemical change causes new substances to be formed. The new substances have different chemical properties from the original substance. Changes in the state or phase of matter, such as the sublimation of dry ice (solid carbon dioxide), are physical changes because the chemical compositions of the substances do not change. Sublimation is the change of an object from a solid-state directly to a gaseous state.
How does dry ice react in soil?
Dry ice is transformed by sublimation in carbon dioxide gas.
What occurs during dry ice sublimation?
solid ice to vapor
Dry ice is an example of which process?
Dry ice is solid carbon dioxide. The conversion from solid to gas which carbon dioxide undergoes is called sublimination. the process where dry ice is changed into carbon dioxide is called sublimation.
Is dry ice drinks chemistry?
Yes. Putting dry ice in a drink is chemistry. You are witnessing a physical change. Now, if you are asking whether a chemical process is taking place, the answer is no. All that is happening is that the dry ice is changing physical forms: from solid to gas, a phase transition known as sublimation.
What does dry ice iundergo to create fog?
Sublimation
