1 The diagram shows a mercury barometer.
(a) Determine the atmospheric pressure indicated by the barometer. Include the unit.
atmospheric pressure = ............................. unit ............................. [2]
(b) State what is in the space labelled X above the mercury in the tube.

2 The diagram shows a tall can containing water.
The can has three identical holes 1, 2 and 3 on one side, one above the other in a vertical line, as
shown in the diagram.
Water is shown flowing out of hole 2 and hole 3.
, 2
(a) State how the pressure of the water at hole 2 compares with the pressure of the water at
hole 3.
........................................................................................................................................... [1]
(b) Draw on the diagram to show the stream of water flowing from hole 1. [1]
[Total: 2]
3 The diagram shows a steel container fitted with a liquid manometer. There is a gas in the container.
2
The area of the steel container in contact with the bench is 80 cm . The total weight of the steel
container and its contents is 60 N.
Calculate the pressure that the steel container exerts on the bench.
2
pressure on the bench = .............................................. N / cm [3]
