What happens when you pour hot water into a cold glass?
When we pour hot water in a cold glass the part of glass which comes in contact of hot water starts expanding but other than that part doesn’t expand at the same instant , so it breaks due to the phenomenon of thermal expansion . (The same thing occurs, when we pour coldrinks in normal glasses during summer .)

What’s the temperature difference between hot and cold water?
The other way around is a lot harder to get as great of a temperature differential. You could put your glass in the freezer, and get it down to 0 degrees maybe, but how hot can you get your liquid. The boiling point of water is only 212 degree F, almost 200 degrees lower than your oven temperature.
