Gases become more soluble in water when which of these is increased?

Answer 1

Gases are soluble in liquids only when there is a constant volume. Take soda, for example. If you open the lid, it loses its carbonation and essentially becomes "flat." That's because CO2 is a volatile gas, meaning its natural state is in the gas phase. Gases, with their random movement, will eventually attain enough energy, through things like collision or increasing the temperature (like when the soda gets warmer, it gets more flat as well), to have the gases escape from the aqueous phase back into its more stable gas phase.

Answer 2

In gases, solubility increases at pressure increases. As the gas molecules are packed into a smaller space, some dissolve to compensate for the decrease in volume. Thus, pressure and solubility of gases are directly proportional.

Answer 3

The solubility of gases increases when pressure is increased. This is described by Henry's Law, which states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid.

Answer 4

pressure of the gas :)
