Up to what temperature can Pyrex glass pipe resist heat?

350°F
400°F
450°F
500°F

The correct answer is: 450°F

Pyrex glass pipes are made of borosilicate glass, which is known for its resistance to temperature changes and heat. In general, it can withstand temperatures of up to 450°F. Options A and B are incorrect because Pyrex glass is capable of withstanding higher temperatures. Option D is incorrect because while Pyrex glass can withstand temperatures close to 500°F, it is not recommended to heat it up that high for an extended period of time. Additionally, heating up the glass to a temperature close to its limit can increase the risk of premature cracking or breaking.
