1) Dissolving is a a) irreversible process b) reversible process 2) After you dissolve a substance in a liquid, you can get it back by a) evaporating the liquid b) filtering the liquid c) condensing the liquid 3) If you increase the temperature of a liquid, the solid will a) not dissolve at all b) dissolve slower c) dissolve faster 4) If you don't stir the mixture during dissolving, the process will be  a) faster b) slower c) the rate (speed) of dissolving stays the same 5) If you add powdered sugar instead of crystal sugar the dissolving will be a) faster b) slower c) the rate (speed) of dissolving stays the same 6) If you decrease the temperature of a liquid, the solid will a) dissolve faster b) dissolve slower 7) If you dissolve maximum amount of a solute in a solvent a) the solution is reversible b) the solution is evaporating c) the solution is saturated 8) The dissolved solid is called a a) solvent b) solute c) solution 9) The liquid that dissolves a substance is called a a) solvent b) solute c) solution 10) If you dissolve a solid in a liquid you prepare a a) solvent b) solute c) solution 11) Which of the following increases the rate at which a solid dissolves in a liquid? a) Using larger crystals instead of powder b) Stirring the solution c) Decreasing the temperature d) Leaving it still 12) Why does powdered sugar dissolve faster than sugar cubes? a) Powder has more surface area exposed to the solvent b) Powder is colder than cubes c) Powder has fewer molecules d) Powder repels the liquid e) Powder has less surface area exposed to the solvent 13) How does increasing the temperature of the solvent usually affect the dissolving of a solid? a) It slows it down b) It has no effect c) It speeds it up d) It prevents it from dissolving 14) Which action would help salt dissolve faster in water? a) Using large crystals and cold water b) Stirring and using hot water c) Leaving the solution still and using sugar cubes d) Using cold water and large beaker 15) What factor does NOT affect the rate at which a solute dissolves in a solvent? a) Surface area of the solute b) Temperature of the solvent c) Color of the solid d) Stirring the solution
