What about thermoses? You put hot stuff in and it stays hot. You put cold stuff in and it stays cold.How does it know?

if you're not trolling then the answer is, it doesnt knowi sometimes ask people a simple question about hot vs cold. When you put ice in your drink, is the ice cooling the drink or is the drink warming the ice?my answer is the drink is warming the ice because there is no such thing as "cold" energy, cold is merely the absence of heat and at all times, nature is attempting to maintain balance.Therefore, the thermos is only trying to prevent/delay that balance from happening by putting barriers (insulation)

Well, I remember from science class that when you put an ice cube into a drink, the ice is absorbing heat energy from the surrounding drink, thus heating up the ice cube and turning it into water while cooling down the drink because it's draining the heat.
