When mixing solids in liquids, an increase in temperature means...

• increase in solubility

• decrease in solubility

When mixing gases with liquids, an increase in temperature means...

• increase in solubility

• decrease in solubility

True or false: The smaller the particle size(large surface area per unit volume) means...

• increase in solubility
• decrease in solubility

Which will dissolve faster crushed table salt or crystal of table salt?

• decreases

True or False: Smaller particles have more edges and corners where the solvent can being contact.

• True
