Question

what happens when dry ice stays still

Answer 1

When dry ice is left undisturbed and stays still, it slowly sublimates. Sublimation is the process where a solid directly changes into a gas without going through the liquid phase. In the case of dry ice, which is solid carbon dioxide, it gradually transforms from a solid to carbon dioxide gas. This process occurs due to the temperature difference between dry ice (-78.5 degrees Celsius or -109.3 degrees Fahrenheit) and the surrounding environment. As the dry ice sublimates, it releases a white vapor, which is a visible form of carbon dioxide gas.
