Final answer:
The statement is true; hot glass looks similar to cold glass, which necessitates caution in handling to avoid injuries. Pyrex glass, known for its lower thermal expansion, is less prone to breaking from thermal stress.
Step-by-step explanation:
The question refers to handling hot and cold glass, and the statement is True. It is crucial to handle them differently because it is hard to distinguish between hot and cold glass just by looking at it. Hot glass does not appear noticeably different from cold glass. Handling glass without knowledge of its temperature can lead to burns or other injuries. In addition, different types of glass, like Pyrex®, expand less and hence experience less thermal stress when subject to rapid temperature changes. This makes Pyrex less likely to break when exposed to such conditions, unlike other types of glass that might crack or shatter due to thermal stress. Safety precautions, such as using gloves, goggles, and safety aprons, should be followed when working with glass, especially under changes in temperature.
