Water, condensed from the air, onto the glass. The rate of condensation depends on the relative humidity and the temperature differential between the glass and the air.
I've had a slight headache after drinking a very cold drink too quickly on a hot (sweaty) day.
The difference in temperature causes the inner glass to expand while the outer glass remains the same size, breaking the vacuum seal between them and allowing them to separate easily. It's important to be cautious with the hot water to avoid accidentally shattering the glass if it is too cold or thin.
Put cold water inside the glasses. Dip the outer glass into hot water. The outer glass expands, the inner glass contracts.
The process responsible for water droplets forming on the outside of a glass of lemonade on a hot summer day is condensation. When the warm, humid air comes into contact with the cold surface of the glass, the temperature of the air near the glass decreases. This cooling causes the water vapor in the air to lose energy and transition into liquid form, resulting in the formation of tiny water droplets on the glass's surface.
Most types of glass aren't designed for hot drinks. When one part of the glass is suddenly heated up other parts might not be, the stress put on the brittle glass causes it to crack or shatter possibly spraying people near by in hot liquid.
because the glass will pop if you put the very hot water into the glass
Because the glass shatters
When hot water is poured into a drinking glass, the temperature difference between the hot water and the glass can cause uneven expansion, leading to stress in the glass material. If the stress exceeds the glass's structural integrity, it can result in the glass breaking. Rapid heating can also cause thermal shock, further increasing the likelihood of the glass breaking.
you can if you put a spoon it the glass first before pouring in the hot liquid, otherwise the glass might crack
The moisture in the warm air collects on the cold glass. When enough moisture collects, it forms beads of water that run down the side of the glass.

No it is not.
Pouring hot liquids into a drinking glass can cause the glass to expand rapidly, leading to cracks or shattering. This sudden change in temperature can also cause the glass to break, posing a safety hazard. It is better to use heat-resistant glassware or let the liquid cool slightly before pouring it into the glass.
Yes, it is true. Putting boiling water in a drinking glass can create thermal shock, causing the glass to break. The sudden change in temperature can expand or contract the glass too quickly, leading to cracking or shattering. It is safer to use heat-resistant glassware designed to withstand high temperatures.

When we pour very hot water into an empty glass, the inner surface of the glass will expand as matter expands when heated. But the inner surface of the glass will expand more than the outer surface of the glass because more heat is applied to the inner surface of the glass.
