What else can I help you with?
If you let dry ice evaporate?
If you let dry ice evaporate, it will turn directly from a solid to a gas without passing through a liquid phase. This process is called sublimation. Dry ice sublimates at a temperature of -78.5 degrees Celsius.
Why does dry ice evaporate faster than a regular ice cube?
Dry ice is frozen carbon dioxide, totally different from ordinary ice, which is frozen water. Dry ice is much colder than water ice, thus evaporates quicker at room temperature. DO NOT TOUCH DRY ICE! It can hurt you badly.
Which statement describes the phase change that occurs when dry ice is placed in an open container at room temperature?
The dry ice will sublimate, which means it will change from a solid directly to a gas without passing through the liquid state. This process occurs due to the low temperature of dry ice (-78.5°C) compared to room temperature, causing it to transition directly to carbon dioxide gas.
What is added to dry ice to make it change?
Essentially, dry ice will simply change from a solid straight to a gas through sublimation at room temperature. Nothing is needed to change the state of matter of dry ice except a higher temperature.
Could dry ice change the temperature in a small room?
Perhaps a small amount.
Why do pieces of dry ice gradually get smaller when left at room temperature?
Dry ice is solid carbon dioxide that sublimes, meaning it directly changes from a solid to a gas without melting into a liquid. At room temperature, the dry ice sublimes into carbon dioxide gas, leading to its gradual disappearance and decrease in size over time.
Is the temperature of ice water lower than the temperature of dry ice in alcohol?
No. The temperature of dry ice is far lower than that of ice water.
How is dry ice formed?
Dry ice is composed of carbon dioxide, which at room temperature is a gas. The carbon dioxide used to make dry ice is liquefied and then stored and shipped in highly pressurized tanks.To make dry ice, the liquid carbon dioxide is withdrawn from the tank and allowed to evaporate at a normal pressure in a porous bag (a porous material is one through which air and water molecules can pass). This rapid evaporation consumes so much heat from the surrounding air that part of the liquid carbon dioxide freezes to a temperature of -109° Fahrenheit (-78° Celsius). The frozen liquid is then compressed by machines into blocks of "dry ice" which will sublimate (return to the gaseous state) when set out at room temperature."Metals And Other Materials - How Is Dry Ice Made?."

What would happen if you left dry ice out for a few hours at room temp?
Dry ice will sublime, or turn from a solid state into a gas state at room temperature. Dry ice is the solid form of carbon dioxide. Carbon dioxide at room temperature is a gas. If you left dry ice at room temperature for a few hours, depending how much you have, will completely sublime into gasous carbon dioxide.
What statement describes the phase change that when dry ice is placed in an open container at room temperature?
sublimation
Can dry ice melt in vineger?
No, but it will evaporate (or, more properly) sublimate.
How do you make dry ice without fire extinguisher?
A fire extinguisher does no make dry ice. Dry Ice is the solid form of the gas Carbon Dioxide. At room temperature is you compress (and cool) CO", it turns into solid CO2 (dry ice) without forming a liquid phase.
