Question

the table below shows four samples of carbon dioxide gas and the temperature of the water that they were dissolved in.

sample	temperature of water (°c)
2	73
3	55
4	63

which of the samples most likely had the lowest solubility?

○ 1

○ 2

○ 3

○ 4

Explanation:

For gases like carbon dioxide, solubility in water generally decreases as temperature increases. Sample 1 has the highest water temperature (78°C) among the four samples. So, it is most likely to have the lowest solubility of carbon dioxide.

Answer:

1 (Sample 1)
