True.

Explanation:

The ice can become water vapor without having reached the first liquid phase. This process is called sublimation and consists of the passage of a solid to the vapor state without first passing through the liquid state, that is, as the dry ice is heated, it is transformed directly into water and not liquid water.

When heat is supplied to an ice body (0 ° C), for example, the temperature remains constant until the ice melts. The energy is used to break up the internal crystalline structure of the ice and melt it. If that heat is high enough it can turn the ice directly into the water vapor.
