🌡️ Temperature tells us how hot or cold a thing is.
🔥 Heat is energy. Heat is the reason temperature changes.
➡️ Heat always moves from the hotter place to the cooler place.
📉 Hot water loses heat to cooler surroundings → it cools down.
📈 Cold water gains heat from warmer surroundings → it warms up.
⏸️ Same temperature? No heat moves, so nothing changes.
