What would you get more energy from - hot food or cold food of the same kind?
Just a thought on this, it takes more energy when you're exercising and drink a very cold drink to digest it because your body has to warm it up first. As opposed to a luke warm drink that requires less energy units to be processed and digested by the body.
The opposite condition from cold is hot. The opposite of cold as a experienced condition (the cold) would be the heat. Cold and hot express relative variations in thermal energy (molecular energy), so that an object cannot not possess greater cold, but rather less heat. *The opposite of a cold person would be warm, kind, or considerate. hot
