Feedback

1

The temperature is above the Saturation Temperature for this pressure, so it is a Superheated Vapour.

2

Temperature is below the Saturation Temperature for that pressure, so is a Subcooled Liquid. 1 bar is the pressure of the atmosphere around us right now, and at this pressure, water boils at 100°C.

4

It is described as steam (a vapour), and has a dryness fraction, so is a Wet Vapour.

5

Temperature is below the Saturation Temperature for that pressure, so is a Subcooled Liquid.

6

T is equal to the Saturation Temperature at that pressure, so it could be any of the three states depending on other factors.

7

It is described as steam (a vapour), and has a dryness fraction, so is a Wet Vapour.

8

It is a "Saturated Vapour" with no dryness fraction, and not superheated.

9

T is equal to the Saturation Temperature at that pressure, so it could be any of the three states depending on other factors.

10

T is equal to the Saturation Temperature at that pressure, so it could be any of the three states depending on other factors.

You can integrate the game into an LMS compatible with LTI 1.1 or LTI 1.3 such as Canvas, Moodle, or Blackboard. This way, the scores will be automatically saved into the platform’s gradebook.
