You get what you pay for.
Drop it
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.
get glass and brake it
Temperature affects glass like it does anything else. If the temperature of glass gets high enough, it will melt. There is not a typical melting point for glass, as it depends on the composition.
I had to hit the brake before the glass would break.
ice melt in the room temperature
Glass breaks when it is stretched, bent or distorted past its tensile flexible limit.
It is not possible. You call the substance a solid if it is so at room temperature. It is not possible for a solid (at room temperature) to also be as a liquid at room temperature.
Glass expands and contracts according to the ambient temperature.
No, it has to be higher.
The cold water reduces the temperature of the glass. The cold glass reduces the temperature of the air around the glass. The amount of moisture in air is temperature dependant hotter air can contain a higher moisture content. If the air temperature is reduced the water condenses. In this case the cold glass reduces the air temperature in contact with the glass, this results in the condenstion of moisture from the air, and water droplets are formed.
