I was thinking today about why air feels coller when you stick your head out of a moving vehicle and why it feels warmer when stationary. I came to the conclusion the cooling properties of the air are greater when the car is moving as a larger volume of air is being passed over my per unit of time. Thus the air feels cooler as it is conducting more heat away from my skin unit of time. My friend said - its because the temperature of the air has changed. And i was stuck because we differed over the definition of the word temperature - he argued that temperature meant rate of conduction of stored heat where I took it to mean the amount of stored heat. The issue was further clouided as we argued over the correct term to fit this sentence 'If we have some wood and metal at the same ________ the metal will feel hotter as it conducts faster'. Help the argument be settled - please!!
