How Does Heat Move? — Passage
Have you ever touched a metal spoon left in a hot bowl of soup? It feels warm, right? That’s because heat moves from one place to another. This movement is called heat transfer.
Heat always flows from something hot to something cold. There are three main ways that heat can move: conduction, convection, and radiation.
Conduction happens when heat moves through something solid. Think about that hot spoon again. The soup heats the end of the spoon in the bowl. Then the heat travels through the spoon to your hand. Metals are good at conduction.
Convection happens in liuids and gases. When water boils in a pot, the hot water at the bottom rises, and the cooler water at the top sinks. This makes a circular motion. That motion moves the heat around. This is how warm air moves through your home with a heater or fan.
Radiation is heat that travels in waves. You don’t need anything solid or liuid for this. The Sun warms the Earth using radiation. You can feel radiation when you sit near a campfire or under a heat lamp. The heat travels through the air to reach you.
Heat transfer is all around us. It cooks our food, warms our homes, and even helps our bodies stay at the right temperature. Understanding how it works helps us use energy better and stay safe.
Fun Fact: Penguins huddle together to stay warm in freezing weather. They use body heat and reduce heat loss by blocking the cold wind—nature’s teamwork in heat transfer!
