Because one of the two endothermic steps (separation of the solute particles) in the solution-formation process is unnecessary.
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.
Oxygen, nitrogen, and various other gases are always present in the air. These gases are essential for supporting life on Earth.
The densities of these gases are virtually identical.
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.
When brass is dissolved in acid, the gases released may include hydrogen gas (H2) and potentially carbon dioxide (CO2) if carbonates are present in the brass alloy. The exact composition of gases released can vary depending on the specific acid and composition of the brass.
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.
Dissolution of gases in water is a physical change.
At higher pressure the dissolution of gases in liquids is increased.
The burning of natural gas is an exothermic process.
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.
I suppose that the dissolution is faster in fresh water but the differences are minimal.

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.
