Answer:
b. Decreasing its temperature.
Step-by-step explanation:
Solubility of Ideal Gases
The kinetic molecular theory (KMT) of ideal gases outline the behaviour of gas particles:
- the volume of individual gas molecules is negligible compared to the volume of the container
- there are neither attractive nor repulsive forces between gas molecules
- gas molecules have high translational energy, and they move randomly in all directions in straight lines
- when gas particles undergo a collision, the collision is elastic
- the average kinetic energy is directly proportional to the temperature
For a substance to go into solution, or dissolve, it must develop strong intermolecular forces with the solvent.
Since gas particles have high kinetic energy, it has trouble forming intermolecular forces with itself and other particles.
To increase the solubility of a gas, we must decrease the kinetic energy of the solvent particles.
Thus, we must decrease the temperature of the drink.
