Detailed Solution

The statement, “Sublimation is the process of conversion of a matter from its liquid state to gaseous state at specific conditions of temperature and pressure.” is false.

Some solids undergo a change in state, directly from solid to gaseous state, without changing to the liquid state and vice-versa. This process is called sublimation.
