They give us the boiling point of a substance and two temperatures, one initial and one final.
The first temperature, 25°C, is below the boiling point, 145°C, which means that the substance is initially in a liquid state.
The final temperature is a temperature above the boiling point, 155°C. This means that the substance will be in a gaseous state.
So what we can predict is that the substance initially in liquid state changes to a gaseous state due to the increase in temperature.
