Hey everyone. So here we have two medals of the same weight And they are heated to 78°C left in separate vacuum flask After 30 minutes medal a 75°C metal B 76.3°C. They were asked why did the two metals have different temperatures after minutes? It's gonna be a because they have different specific heats. This means that one metal can store more heat than the other, even if they started with the same temperature, one will release more heat. Thanks for watching my video, and I hope it was helpful.
