What is Warmer object loses heat?

Warmer objects lose heat when they're next to something cooler, just like ice cream melts faster on a hot day than in the freezer.

Imagine you have two cups of juice: one is hot, and the other is cold. If you put them side by side, the hot juice will slowly give away its warmth until both are about the same temperature. That’s because heat always wants to spread out, it moves from where it's warmer to where it's cooler.

Think of heat like a group of kids playing tag. The hot cup is full of energetic kids running around, while the cold cup has sleepy kids barely moving. When they’re together, the energetic kids from the hot cup will run over to join the sleepy ones, and as they do, they’ll make the cold cup warmer, and themselves cooler.

This is what happens in real life too: your hot soup loses heat when it’s on the table, and your cold drink gets warmer when you put it in a warm room. It's like the heat is going on a little vacation from the hot things to the cool ones!
