Question 9 • Physical Science

Naomi has increased the pressure on a solution of liquid and gas in a closed container. What will this do to the gas in her solution?

Answer
A
decrease the temperature
B
increase the temperature
C
increase the amount
D
decrease the amount

Explanation

Increasing pressure makes more gas dissolve in the liquid. This follows Henry’s law: at a given temperature, the amount of dissolved gas increases as the gas pressure above the solution increases. So the amount of gas in the solution will increase, not its temperature.
