What does this picture have to do with thermodynamics? The bucket on the left contains liquid nitrogen boiling at 77 Kelvin (-196 Celsius or -320 Farenheit).
After a piece of banana and a section of rubber hose have been immersed in
the nitrogen for a few seconds, their properties change so that the banana
can be used to hammer the rubber into a wooden block. (Don't try this at home!)
