Glass Cup When Poured By Hot Water Can Break Cause
Discussion When hot coffee is placed in a glass, the temperature of the glass will rise and cause expansion. The inner glass expands faster than the outside so that the inner glass presses against the unexpanded outer glass causing the glass to crack. So, this is caused by the expansion of the inner glass wall, while the outer glass wall has not yet expanded. So, the correct answer is C.

Visually, in its presentation, the glass material used must also be considered. For example, hot drinks are recommended to be served in glasses rather than plastic cups. However, when pouring hot water into a glass container, it is often seen that the glass used suddenly cracks/breaks. The glass is quite thick though. Surprisingly, when the same hot water was poured into a thin glass, nothing happened. Why is this happening?
A substance will increase in size (expand) when heated. This happens because when heat is applied, the energy of these particles increases. Because of this, these particles will move randomly and occupy more space.
When hot water is poured into a glass, the energy of the hot water passes through the walls of the glass from the inside out. The expansion process is in the same direction as energy propagation. If the glass wall is thin, then the heat energy will unite all parts of the glass wall simultaneously. So the glass wall can’t be broken.
If the glass is made of glass that is thick enough, the heat energy will take longer to spread throughout the glass. While the inside has expanded a lot, the glass exterior hasn’t expanded. As a result, the inner glass wall will be pushed out and cause the glass to crack/break.
What Happens If A Glass Is Put In Hot Water Then Suddenly Cold Water Is Added Then
The hotter the water is poured into the glass, the more likely it is to break. Unless the water is very hot, the energy supplied isn’t enough to expand the glass significantly. So the glass will not break even though it is thick.
To reduce the risk of breaking the glass, we can put a metal spoon on it. Metal is a good conductor of heat, so more energy from the hot water is absorbed by the spoon. This will reduce the energy that is channeled through the glass wall.
