Question

What is the physical state of the water at (a) 250◦C (b) 100◦C

Answer 1

Answer:

(a) Steam (gaseous)

(b) Liquid that starts to change into vapour

Explanation:

waters boiling point is 100°c . So it starts to change into steam at this temp. But water isn't totally gaseous state at this time. It just starts to change. So it is a liquid that has started to evaporate.

As for 250°c , this temp is way more than the boiling point so by this temp all the water is changed into steam, thus gaseous state is obtained.
