When glass cools down, its molecules slow down and pack closely together, causing the material to solidify. As the glass cools further, it becomes rigid and retains its shape, transitioning from a liquid to a solid state. This process is known as glass transition.
When glass melts, the solid structure breaks down and the glass becomes a viscous liquid. The molecules rearrange and flow freely, allowing the glass to take the shape of its container. As it cools, the glass solidifies back into its rigid form.
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.
Condensation on a glass surface occurs when warm, moist air comes into contact with the cooler surface of the glass. The air cools down upon contact with the glass, causing the water vapor in the air to condense into liquid water droplets on the surface of the glass.
Glass can get ripples due to the manufacturing process or from uneven cooling. During the production of glass, if the material is not evenly distributed or if it cools at different rates, ripples can form on the surface. This can also happen during the bending or shaping of glass, causing the surface to distort.
Slumping is a glass forming technique where glass is heated until it becomes soft and then slumped over a mold. The glass takes the shape of the mold as it cools and solidifies, creating a new form. Slumping can be used to create various glass objects such as plates, bowls, and vases.

No. Granite cools from magma deep underground. Volcanic glass cools quickly at or near the surface.
what happens is that the air(vapor) changes state back to liquid when it hits the cold glass since the temperature lowers the energy of the gas and transforms it back to a liquid.
When glass is melted, it becomes a molten liquid that can be shaped and molded into different forms. As it cools down, it solidifies and retains the shape it was given. Melting glass also helps to remove any impurities present in the material.
guess
It expands and cools
Metal.
as air cools, the space it occupies becomes less. this result in an increas density
As air cools, the space it occupies becomes less. This results in an increase in density.
Glass is a solid. It is melted silicon that has cooled quickly. A mineral that cools slowly can become a crystal.
Obsidian is a form of glass. Glass can only form when material cools from a molten state.
It forms igneous rock.
