Unfortunately, this depends upon whose Pyrex you are considering. The original Pyrex was a borosilicate glass, which has a low thermal expansion. The Trademark owners have allowed the name to be used nowadays by some manufacturers who use tempered soda-lime glass. But some licensees still use a borosilicate glass.
What else can I help you with?
What is the refraction for these 2 materials germanium and Pyrex?
The refractive index of germanium is around 4.0 in the infrared region, making it useful for optics in thermal imaging systems. Pyrex, on the other hand, has a refractive index of around 1.5 in the visible spectrum, commonly used for glassware and lenses due to its low thermal expansion.
What is the increase of the volume of a substance by the increase of temperature called?
The increase in volume of a substance due to an increase in temperature is called thermal expansion. This occurs because as the temperature of a substance rises, the particles within it gain energy and move more, causing them to spread out and increase in volume.
The change in an objects volume that occurs when heat is added is called?
thermal expansion
Why does not a pyrex glass crack when hot water is poured on it?
Pyrex glass is made with a specific type of thermal treatment that makes it more resistant to thermal shock. This allows it to withstand sudden changes in temperature, such as pouring hot water on it, without cracking. Additionally, the chemical composition of Pyrex glass helps it to expand and contract more evenly when exposed to heat, reducing the likelihood of cracking.
What are not an example of thermal expansion?
Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
Is All glass made from Pyrex?
No, not all glass is made from Pyrex. Pyrex is a brand name for a type of borosilicate glass that is known for its durability and resistance to thermal shock. There are many other types of glass with different compositions and properties used for various applications.

Why Pyrex glass stand the shock of a sudden change in temperature?
Pyrex glass is made with borosilicate, which has a lower coefficient of thermal expansion compared to regular soda-lime glass. This means it can withstand sudden changes in temperature without shattering due to its ability to expand and contract evenly. The unique composition of Pyrex makes it more resistant to thermal stress, which is why it is commonly used for cooking and laboratory glassware.
What is pyrex glass?
It is a glass formulated to resist thermal shock.
Where can you purchase the reheatable thermal heat pack for your Pyrex casserole?
I have found them on Amazon.com
Why is pyrex glass less likely to crack when subject to a rapid temperature change?
Pyrex glass is less likely to crack when subjected to rapid temperature changes because it is made with borosilicate glass, which has a higher thermal shock resistance compared to regular glass. The composition of borosilicate glass allows it to handle quick temperature changes without breaking due to its low coefficient of thermal expansion.
Is pyrex a metal?
No, Pyrex is not a metal; it is a type of glass. Specifically, Pyrex is made from borosilicate glass, which is known for its ability to withstand high temperatures and thermal shock. It is commonly used in kitchenware and laboratory equipment due to its durability and resistance to chemical reactions.
Did anything happen to the surface of the pyrex test tube in this flame?
Pyrex is resistant to thermal shock and can withstand high temperatures, so the surface of the Pyrex test tube likely did not change in the flame. It should remain unaffected under normal laboratory conditions.
What is the increase of the volume of a substance by the increase of temperature called?

Liquids expansion by heat?
Yes as friend Des Dichado pointed out liquids do have thermal expansion.
How does thermal expansion affect a bridge?
A bridge must have expansion gaps or else they will waver when they expand in warm temperatures. This is thermal expansion
