解題步驟

1. Understand the question

   select all the reasons for checking glassware for cracks or chips prior to use.
   □ chips or cracks will make your experiment take longer.
   □ you could cut yourself on glassware that has a chip.
   □ chips or cracks can make the glassware more likely to break during use.
   □ chips or cracks will change the outcome of the experiment.
   done

2. Brief Explanations
   • Chips/cracks do not slow experiments directly.
   • Sharp chips pose a physical cut hazard.
   • Damaged glassware is structurally weaker, prone to breaking during use (e.g., with heat, pressure, or handling).
   • Unless the damage causes leaks/volume inaccuracies, experiments may not be affected, so this is not a universal reason.
3. Final answer
   • You could cut yourself on glassware that has a chip.
   • Chips or cracks can make the glassware more likely to break during use.
