Which physical change occurs when carbon dioxide snow disappears?
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 physical change occurs in carbon dioxide snow disappears?
When carbon dioxide snow (solid CO2) disappears, it undergoes a process called sublimation. This change involves the transition from a solid state directly to a gas without passing through a liquid phase. As the temperature rises or pressure decreases, the solid CO2 absorbs heat and transforms into carbon dioxide gas, which disperses into the surrounding air. This phenomenon is commonly observed with dry ice used in various applications.
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

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

Is freezing carbon dioxide to make dry ice a chemical change?
No, it's a physical change.
Is it physical or chemical change when acid on limestone produces carbon dioxide gas?
It is a 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 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-
Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.
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.
