Question

При наливании горячей воды толстостенный стакан быстрее трескается чем тонкостенный. Почему?​

Answer 1

Ответ: Из-за того, что  тонкостенный равномернее прогревается

Объяснение: При нагревании стакана, он накапливает энергию воды и передаёт её воздуху. Так как тонкостенный стакан имеет лучшую теплопроводность, он получает тепло и практически сразу передаёт всю накопленную энергию в воздух, в то время как толстостенный стакан не успевает на столько быстро передавать в воздух всю энергию, в связи с чем он начинает разрушаться

Answer 2

Why does a thick-walled glass crack faster than a thin-walled glass when hot water is poured into it?

When hot water is poured into a glass, the glass expands due to the increase in temperature. However, different types of glass have different thermal expansion coefficients, which can affect how they respond to temperature changes.

Thick-walled glasses tend to have a higher thermal expansion coefficient compared to thin-walled glasses. This means that when hot water is poured into a thick-walled glass, it expands more rapidly and to a greater extent than a thin-walled glass. The uneven expansion can create stress within the glass, leading to cracks or even breakage.

Additionally, the rate at which heat is conducted through the glass can also play a role. Thick-walled glasses tend to conduct heat more slowly than thin-walled glasses. As a result, the temperature difference between the inner and outer surfaces of the glass can be greater in a thick-walled glass, further increasing the stress and the likelihood of cracking.

It's important to note that the specific design and composition of the glass can also influence its behavior when exposed to hot water. Different types of glass may have different properties and may respond differently to temperature changes. Therefore, it's always a good idea to follow the manufacturer's instructions and guidelines when using glassware with hot liquids.
