[S1 Science and up - Water & Three States of Matter]
Kept you waiting, huh?
You might have questions during your Science class, such as "why does the question assume room temperature and pressure?"
Water can exist in all 3 states at once, when the right pressure and temperature is achieved. All pure substances is capable of this state, in theory, but water is the most readily available and safest example to use in this experiment.
You might remember in a much earlier post (around 2019) that water was able to boil even when it's not at the boiling point, as demonstrated by Grady. (here's a refresher for that video)
This pressure-temperature graph that physicists charted was the one Grady referenced in his hydrostatics experiment. The more you know.
