# Cooling liquid inside a pint glass with an aluminium plate

Basically the title.

If I have a very cold aluminium plate (don't know the temperature, but enough to have frost) and put a glass pint glass on top of it with liquid inside of it will that cold transfer enough to the glass and then to the liquid to keep it cool?

I know glass is an insulator and electrons don't move as fast but i'm just looking to keep a drink relatively cold, not freeze it. Is this possible to figure out or will I just have to trial and error it?

• It is possible. Is that all you wanted to know? – Chet Miller Aug 29 '18 at 20:45
• Is it possible for the glass to transfer enough heat to the aluminium giving the low surface area to keep the liquid inside the glass cool. – user2570937 Aug 29 '18 at 23:41

Maybe I can suggest to put the aluminium plate above the glass because I think the air under the plate will cool down and will reach the surface of the drink. Maybe with the $pV = nRT$, as the temperature on the air inside the glass cools down, volume can't change because of the rigid behaviour of the glass and the plate, so pression will decrease: in this way the atmospheric pressure would be higher than that one in the little air on the glass and the plate will better plug the glass.
