Figure 2 shows the concentration of carbon dioxide in the atmosphere above Hawaii from 1960 to 2010 - Edexcel - GCSE Chemistry Combined Science - Question 2 - 2016 - Paper 1

To find the increase in the volume of carbon dioxide in 1 m³ of atmosphere from 1960 to 2010, we first identify the values from the graph:

1. In 1960, the concentration of carbon dioxide was approximately 320 cm³/m³.
2. In 2010, the concentration was approximately 390 cm³/m³.

Next, we calculate the increase:

$ext{Increase} = 390 ext{ cm}^3/ ext{m}^3 - 320 ext{ cm}^3/ ext{m}^3 = 70 ext{ cm}^3/ ext{m}^3$

Thus, the increase in the volume of carbon dioxide in 1 m³ of atmosphere from 1960 to 2010 is 70 cm³.
