because it evaporates
The water will not "disappear"; it will evaporate. If it's hot, water will evaporate faster.
because the glass will pop if you put the very hot water into the glass
Condensation may form on the side of a drinking glass on a hot day. This occurs when the cold surface of the glass comes into contact with the warmer air, causing the water vapor in the air to cool and collect on the surface of the glass.
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.
Condensation of the cool air on the hot glass.
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.
The exact same reason a glass filled with ice water sitting on a table has CONDENSATION forming on the outside of the glass .. The ambient temperature is HIGHER then the glass and thus the dripping
When hot water is poured into a glass, the glass expands slightly due to the heat. This can create stress within the glass, potentially leading to cracks or breakage, especially if the glass is thin or has imperfections. It is best to use tempered glass or heat-resistant glassware for pouring hot liquids to minimize the risk of breakage.
Water in a boiling pot changing to a gas IF you leave a glass of water out on a hot day, it will be gone in a couple of hours
The glass of a kerosene lamp while glowing is hot. When water falls on it, there is a sudden change in temperature, which causes the glass to break.
Yes, at first it will. But it will easily come off with hot water and if you let the glass object sit with the hot water in it.
Yes, condensation could form on the outside of a beaker full of hot water if the surrounding air is cool enough to cause the water vapor in the air to condense on the cooler surface of the beaker. This is similar to how condensation forms on a cold glass of water on a warm day.
