Question

What you can do with hot liquid glass​

Answer 1

$\huge \colorbox{lime}{Answer}$

When you pour hot water into a glass (which is at room temperature), the inner layer of the glass will absorb heat. When a material absorbs heat, it expands. If the water is really hot, the glass will definitely crack.

Hope it helps u! :)

Answer 2

Answer:

When you pour hot water into a glass (which is at room temperature), the inner layer of the glass will absorb heat. When a material absorbs heat, it expands. ... If the water is really hot, the glass will definitely crack.

This temperature difference will cause the inner layer of the glass to expand significantly more than the outer layer. This difference in the amount of expansion exerts a tremendous amount of pressure on the outer layer. If the glass is unable to hold up against the large pressure, the glass will crack. The magnitude of the temperature difference between the inner and outer layers will determine the likelihood of the glass cracking. If the water is really hot, the glass will definitely crack.

If you want to prevent the glass from cracking, you should aim to reduce the temperature difference between the inner and outer layers. Here are some ways to do that:

Pour the hot water (very) slowly into the glass.

Put a metal spoon in the glass to conduct away some of the heat. The temperature of the water will drop and the inner glass layer will face a slightly cooler body of water.

Warm up the glass gradually by filling it with 50% room temperature water and 50% hot water. Pour it out and replace with 60% room temperature water and 40% hot water. And so on.. (Well, you get the idea)
