Thermodynamics, You Take It From Here, Part 26
It’s a bitterly cold Chicago winter outside, where the air hurts your face. A customer approaches, holding a tray of bottles of apple juice.
Customer: “Excuse me. If I leave these in my car overnight, will they freeze?”
Me: “Yes, ma’am. It’s about -5° outside during the day, colder at night. The juice will definitely freeze if you leave it in the car.”
Customer: “Okay… but what if I wrap them in a blanket?”
Me: “Uh… blankets don’t really keep things warm.”
Customer: “My blanket keeps me warm all the time!”
Me: “Sorry, ma’am, but that’s you generating the heat. The blanket just helps keep it close.”
Customer: “So… the blanket won’t help?”
Me: “Not unless apple juice suddenly learns how to produce body heat.”
Customer: “Oh, wait, it’s apple cinnamon juice! Those stay hot, right?”
