What does 'soluble' mean?
The substance can disslove in a liquid. The liquid is called a solvent. Generally, solids are more soluble when the temperature increases. The solubility of a gas in particular solvent depends a pressure and temperature

What does the solubility of gas depend on?
The solubility of gas, in a particular sovlent, depends on the pressure and temperature. As pressure increases, more gas molecules dissolve into the solvent. Generally, gases tends to be less soluble as the temperature of the solvent increases.

With most solid solutes, what happens to their solubility as the tmeperature increases?
Most solids become more soluble as the tmeperature increases however some solids are an exception
9 of 11
With most gases, what happens to their solubility as pressure increases?
Gases are more soluble as the pressure increases
