Glass definitely contracts when cooled. If you take a hot glass bottle, perhaps one that has been sitting by a campfire, and toss it into cold water, perhaps a nearby river, you will almost certainly find that the glass fractures as the surface in contact with the cold water tries to contract while the inner glass that is still hot does not.
Yes, when glass is heated, its molecules become more energetic and vibrate more, causing the glass to expand. This expansion is reversible, meaning that the glass will contract back to its original size once it cools down.
Yes, lead does expand when heated and contract when cooled, just like most materials. This property is known as thermal expansion and contraction.
Yes, gases can both expand and contract. When heated, gases expand as the molecules move more rapidly, increasing the pressure and volume. Conversely, when cooled, gases contract as the molecules slow down, decreasing the pressure and volume.
Heat would cause the molecules to speed up movement and expand metals. Glass melts, paper burns, clay would shrink as water vapor escapes, etc.
When temperatures changes this can cause the molecules in an object to contract [ at low temperatures ] or to expand [ high temperatures ] . Glass is a fragile object and if the molecules in glass contract or expand quickly this can cause the glass to break . [SRM] .

No, gasses expand when heated and contract when cooled.
Liquids expand when heated and contract when cooled.
Oil does expand when heated and contracts when cooled.

Matter expands when it is heated.
Glass can be heated without cracking by gradually increasing the temperature and allowing it to cool slowly to prevent thermal shock. This process helps the glass to expand and contract evenly, reducing the risk of cracking.
No, metals always expand when heated and contract only when cooled.
Liquids expand when heated and contractwhen cooled.
Metals contract when they are cooled, and expand when they are heated.
They expand ------- No, normally metals expand when heated.
