When carbon dioxide snow (or dry ice) disappears, it undergoes sublimation, a physical change in which a solid transforms directly into a gas without passing through the liquid phase. As the dry ice warms, it absorbs heat energy from the surrounding environment, causing the solid carbon dioxide to convert into carbon dioxide gas. This process results in the visible disappearance of the dry ice as it transitions from a solid to a gaseous state.

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.
What is the physical change of carbon and snow disappears?
When carbon (soot) is applied to snow, it can absorb sunlight and cause the snow to melt faster. This is a physical change as the snow changes from its solid state to liquid water due to the presence of the carbon.
When carbon dioxide comes from the fuel of the car is it a physical or chemical change?
chemical change
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. a. physical b. chemical?
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. Answer - Chemical Change
Is a heating process onto carbon dioxide a chemical reaction or a physical reaction?
Heating carbon dioxide is a physical reaction because it does not change the chemical makeup of the substance, only its physical state. The heat energy causes the carbon dioxide molecules to vibrate more rapidly, increasing their kinetic energy and leading to a phase change from solid to gas.

Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.

Is it physical or chemical change when acid on limestone produces carbon dioxide gas?
It is a chemical change.
Is freezing carbon dioxide to make dry ice a chemical change?
No, it's a physical change.

Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.
Is combining carbon dioxide and water to make sugar a physical change?
Combining carbon dioxide and water is a chemical change, not a physical change, but it doesn't make sugar. Carbon dioxide and water makes carbonic acid. CO2 + H2O <--> H2CO3-->H+ + HCO3-
When Acid is placed into limestone and produces carbon dioxide gas is this a physical or a chemical change?
This is a chemical change.
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.
