In summary, dissolution gas is the process of a gas dissolving into a liquid, which can occur naturally or artificially. Exothermic dissolution gas releases heat while endothermic dissolution gas absorbs heat. Temperature affects the solubility of the gas in the liquid, with higher temperatures resulting in lower solubility. Dissolution gas can be reversed through degassing, and it has various applications in industries such as food and beverage, pharmaceuticals, and water treatment, as well as in geological processes.

One of the answer explanations in practice book states "student 2 says that the solubility of carbon dioxide in water decreases as the temperature increases. It would be best concluded from this statement that the process of dissolving carbon dioxide in water is exothermic."

Can someone please explain to me how they can make this conclusions based on the statement?

FAQ: Dissolution gas, exo/endo Thermic

What is dissolution gas?

Dissolution gas refers to the process of a gas dissolving into a liquid. This can occur naturally in bodies of water, such as the dissolution of oxygen into lakes and oceans, or it can be artificially induced in laboratory settings.

What is the difference between exothermic and endothermic dissolution gas?

Exothermic dissolution gas refers to a process where the gas being dissolved releases heat, while endothermic dissolution gas refers to a process where the gas being dissolved absorbs heat. This is determined by the energy changes that occur during the dissolution process.

How does temperature affect dissolution gas?

Temperature plays a crucial role in dissolution gas, as it affects the solubility of the gas in the liquid. Generally, an increase in temperature results in a decrease in gas solubility, while a decrease in temperature results in an increase in gas solubility.

Can dissolution gas be reversed?

Yes, dissolution gas can be reversed through a process called degassing, where the gas is released from the liquid. This can occur naturally, such as when a body of water is heated and the dissolved gases are released, or it can be artificially induced through techniques such as vacuum degassing.

What are some applications of dissolution gas?

Dissolution gas has various applications in different industries. In the food and beverage industry, it is used to add carbonation to drinks. In pharmaceuticals, it is used to dissolve gases into liquid medications. It is also used in water treatment to remove gases, such as carbon dioxide, from water. Additionally, dissolution gas is crucial in geological processes, such as the release of gases from molten rock during volcanic eruptions.
