“Cool as a cucumber”


This expression is taken from a literal characteristic of the cucumber.  Being that the inside of a cucumber is actually 20 degrees cooler than their outsides.  All matter has properties of thermal conductivity which dictate how quickly heat will move through the matter. The thermal conductivity of a cucumber is incidentally reported at 0.62 W/m K.
