Dissolution of gases in water is usually exothermic because the strong intermolecular forces in water (hydrogen bonding) help stabilize the solute molecules in the solution, releasing energy in the form of heat. The breaking of intermolecular forces within the gas molecule and the formation of new intermolecular forces with water leads to a lower energy state, resulting in an exothermic process.

Does the solubility of gases increase with temperature increase?
Yes, the solubility of gases generally decreases with an increase in temperature. This is due to the fact that as temperature rises, the kinetic energy of gas molecules also increases, making it easier for them to escape from the liquid.
What is always in the air?
Oxygen, nitrogen, and various other gases are always present in the air. These gases are essential for supporting life on Earth.
What are the solute and solvent both gases?
When both the solute and solvent are gases, the solute is the gas that is being dissolved, and the solvent is the gas in which the solute is dissolved. An example is the dissolution of carbon dioxide (solute) in water vapor (solvent) to form carbonated water.
Why are the rates of diffusion of nitrogen gas and carbon monoxide are almost identical at the same temperature?
The densities of these gases are virtually identical.
Does air pressure affect dissolving of crystals?
Air pressure can affect the rate of crystal dissolution by influencing the equilibrium between the dissolved and solid phases. Higher air pressure can increase the solubility of gases in the solvent, potentially altering the dissolution process. However, the impact of air pressure on crystal dissolution may vary depending on the specific solvent and crystal system involved.
What happenes during dissolving?
For the dissolution of a solid in a liquid this solute is decomposed in atoms or ions; for the dissolution of gases in liquids or dissolution of solids in solids other processes are involved.
Oxygen and nitrogen in water it a chemical or a physical?
Dissolution of gases in water is a physical change.
What kind of solution is affected by pressure?
At higher pressure the dissolution of gases in liquids is increased.
Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gases is an exothermic reaction. This is because it releases energy in the form of heat and light during the combustion process.
Is mixing sodium sulfite and bleach endothermic or exothermic?
Mixing sodium sulfite and bleach is an exothermic reaction. Heat is released during the reaction, making the surroundings warmer. This reaction should be performed with caution as it can produce toxic gases.
Do gases dissolve in fresh or salt water faster?
I suppose that the dissolution is faster in fresh water but the differences are minimal.
Secondary contamination is virtually impossible for hazardaous materials in which state?
gases substances

What can an exothermic reaction do?
An exothermic reaction releases heat energy to its surroundings. This can result in temperature increases, light emission, or the production of hot gases. Examples include combustion reactions, neutralization reactions, and some chemical reactions in living organisms.
