The outside surface of the glass suddenly contracts when hit by cold water, yet the inside is still hot and expanded. So the distorted pressure results in a cracked glass.

Why does a hot glass chimney often cracks when drops of cold water fall on it?
There is a drastic change in temperature, weakening the structure severly
Why does a thick walled glass vessel cracks when hot water ispoured on it?
the water is heated up, its particles gain energy and move faster. this causes the particles to separate further apart. therefore, the volume of the the water increases. i.e. expands. and the thick-walled glass is notrigid enough to hold it. so it cracks.
Why does a cold glass of water leave a ring on the table?
A glass of cold water leaves a wet ring on the table because the heat energy from the outside and the cold glass of water inside the cup then it begins to drip Yea its a little confusing i don't know how to explain it very well
What is the effect when water freezes in to cracks?
The water expands as it is frozen and so the cracks are made wider/bigger :)
How does gravity break down a rock?
Gravity is not a major influence in the decomposition of a rock, unless the rock falls off of a cliff. The main process consists of water seeping into tiny cracks in the rock, then expanding as it freezes. Well, if you want to stretch it, I guess you could give gravity the credit for making the water seep into the cracks.

Why does the hot glass of a kerosene lamp cracks when wet with water?
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.
When water in a glass tube is heated the level of water in the tube?
Falls and then rises

Is a hot glass cracking when placed in cold water a physical change?
it is a physical change because the state of the glass does not change.it cracks because of the rapid change of temperature
How does ice contribute to physical weathering?
It falls in the cracks as water and freezes. As it freezes, it expands, eroding what ever it fell into, whether its concrete or rock.

What type of erosion created chimney rock?
chimney rocks were created by water erosion
Is hot glass cracking when placed in cold water a chemical or physical change?
Physical. The glass expands or contracts depending on temperature, when you put a hot glass into cold water part of the glass cools and contracts while some of it is still in it's hot, expanded state.
What is the purpose of installing a chimney cricket?
A chimney cricket is a sloped structure added to a roof upstream of the chimney to divert rain water away from the chimney. They are installed to reduce the amount of rain water that may enter the house if the sealing around the chimney fails or is less than perfect.
Water freezes in the cracks in rocks. plants grow into the cracks in rocks?
cracks open wider
How does the water get into the ground?
When rain falls to the ground, the water does not stop moving. It seeps into the ground.Water seeps into the ground, such as glass of water poured onto a pile of sand.
