Why does a ceramic bowl keep oatmeal hot longer than a stainless steel bowl?

Metals including stainless steel are excellent conductors of heat. The heat in the oatmeal will be absorbed by the metal bowl and then lost to anything cooler it's in contact with, such as the table top, and the surrounding atmosphere, much faster than would happen with a ceramic bowl.

That is why "heat sinks" used in electronics, notably computers, are made of metal.
