Dry ice undergoes sublimation when placed in warm water, creating a dense fog cloud similar to smoke. This fog effect is used for dramatic purposes in entertainment settings.
Sublimation is the phase change that allows us to see the clouds formed when dry ice is placed in warm water. Dry ice, which is solid CO2, sublimes vigorously in warm water, transitioning directly from a solid to a gas, creating a dense cloud of fog due to the rapid sublimation process.
The cloud formed consists of a low-sinking dense cloud of fog or smoke-like appearance, created by the condensed water vapor above the cylinder when dry ice sublimes. This phenomenon is commonly used in fog machines for various entertainment purposes like theaters, concerts, and haunted houses for dramatic effects.
