Why didn't the same thing happen to glass filled with warm water?

Answer 1

When glass is filled with warm water, the temperature difference between the glass and the water is less extreme compared to cold water. This reduced temperature differential minimizes thermal stress on the glass, preventing it from cracking or breaking. Additionally, glass can often withstand moderate temperature changes without structural failure, as long as the changes are not too rapid or extreme. Thus, the warm water scenario is less likely to induce the same stress that cold water might create in the glass.
