Final answer:
Using chipped or cracked glassware is false and poses safety risks; Pyrex® is less susceptible to thermal stress due to its small coefficient of linear expansion, making it safer for use.
Step-by-step explanation:
The statement that chipped or cracked glassware is okay to use is false. Using damaged glassware in a laboratory setting can present safety hazards. Chipped or cracked glassware may break completely under stress or when subjected to temperature changes, potentially causing injury or contamination of an experiment. Glassware like Pyrex®, which is designed with a small coefficient of linear expansion, is valued for its resistance to thermal stress; it is less likely to shatter when exposed to sudden temperature changes because it expands and contracts less than regular glass. Proper safety protocols dictate the use of gloves, goggles, or safety aprons and that one should never touch broken glass with bare hands.
