Main Question or Discussion Point
Does everything in a given environment have the same temperature. For example does everything inside a refridgerator have the same temperature like a cup of water and a block of steel and a plastic cup. (say the setting of the fridge is at 5 C degrees, if a thermometer is placed on all these items, will they all yield a 5 C degree temperature reading.) Of course assuming these items have been in the environment for a long time and the environment is using energy to maintain this constant temperature.
