Question

C. Predict what will happen to a substance that has a temperature of 25°C

and a boiling point of 145°C if we raise its temperature to 155°C.

Answer 1

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.
