Question

Identify the change of state observed when water is poured on dry ice.

• A. Solid $\to$ Liquid
• B. Liquid $\to$ Solid
• C. Solid $\to$ Gas
• D. Plasma $\to$ Liquid

Answer 1

The correct option is C

Solid $\to$ Gas

Dry ice is solidified carbon dioxide. When we pour water on dry ice, the temperature goes up and solid ice directly turns into carbon dioxide in the form of gas.
The process in which a solid substance directly turns into gas without turning into a liquid is called sublimation.
