Practical work: calculating temperature and pressure
Answers are for parents and teachers.
1
Readings: 0, 2, 4, 6, 8, 10, 8, 2 °C. Find the mean and the amplitude.
Mean 40 : 8 = 5 °C; amplitude 10 – 0 = 10 °C.
2
On a plain it is 745 mm Hg. How many mm Hg at 1800 m?
565
3
On a plain it is +28 °C. What is the temperature at 3000 m?
10
4
Record the temperature near your home or school for 3 days and draw a graph (horizontal – time, vertical – temperature).
The graph depends on the measurements: each point should match time and temperature.
5
Why is pressure high at sea level but low in the mountains?
Because in the mountains the air column above you is shorter and the air is thinner.
