That's not how thermodynamics work. It's either transferring heat more efficiently, or not. But always the same, in both directions.

It's probably "felt thermodynamics". The can feels colder, so it is colder.

How cold a beverage is, is a measure of how quickly it absorbs heat from your hand.

Explain insulation and conduction.

[–] [email protected] 2 points 9 months ago

Insulation and conduction are opposites. Vacuum (empty space) and stagnant air are great insulators, that's how double walled bottles insulate.

Aluminum conducts heat quickly for the same reason it conducts electricity well. It has a relatively low heat capacity too so it doesn't take much energy to heat or cool it so it will more quickly heat or cool its contents.

Toss that alu can in the freezer to cool it quickly, then put it in an insulated colster to keep it cold.
