Andy,

You can fill a pint beer glass with water to the brim
and then slowly introduce a fine pot scrubber wihout
spilling a drop if you are careful. I can't remember
where I first heard that but I didn't believe it until
I tried it.

That seems to say that the volume of copper is *very* small so its
mass would be too. Is there any useful heat exchange between a
negligible mass of copper and .45 litres of air?

I'll add the knowledge to my useful pub tricks list though.
