Summer is here, and already, people are complaining about the heat as is customary. Which begs the question, why does touching cold metal after a day in the summer sun feel so much cooler than touching, let’s say, a book?
Minute Physics explains that our skin can only really tell us how what we are touching makes us feel and as metal is a great conductor the transfer of energy is very fast.
Kinda like how a thermometer can really only measure its own temperature and must touch whatever it is measuring.
Mind blown yet?
