Fig. 1.1 shows a tube full of mercury placed upside down in a dish of mercury. Initially a small piece of glass closes the open end of the tube.
The piece of glass is removed and the level of mercury in the inverted tube falls, as shown in Fig. 1.2.
Explain why the level of mercury in the tube falls.
State what is found at point X in Fig. 1.2.
Describe how the tube of mercury in Fig. 1.2 is used to determine a value for the atmospheric pressure in pascals (Pa). You may draw on Fig. 1.2 if you wish.
