Is it okay to put my tablet inside refregirator? For 10 seconds? Just to cool it down?

I have a tablet, dell tablet. I play minecraft, after few minutes it overheats! My sister told me that to cool down her tablet, she puts in in the freezer.

Refrigerators aren't that cold. Putting it in there for 10 seconds would probably do nothing but maybe make your tablet smell like spoiled food. Even then it's a bad idea. If it's overheating then it probably needs to be serviced or something because it's defective.

A better thing to do is maybe face the back part of your tablet to an electric fan or an airconditioner.

It's fine for 10 seconds, but it's not a good idea because it will get condensation in it. Then it can short circuit.
