Question 28

Easy

Figure 1 shows how atmospheric pressure changes with altitude (height above sea level).

Figure 1: A graph showing atmospheric pressure in kPa against altitude in km. The curve begins at 101 kPa at 0 km altitude and decreases non-linearly, flattening out as it reaches 19 kPa at 12 km altitude.

The data plotted in Figure 1 is shown in the table below:

Altitude (km)	Atmospheric Pressure (kPa)
0	101
2	79
4	62
6	47
8	36
10	26
12	19

Using the data, describe how atmospheric pressure changes with altitude.
