Heat transfer is a basic idea in thermodynamics. It happens in three main ways: conduction, convection, and radiation. Let’s explain each one!
Conduction is when heat moves through direct contact.
Imagine a metal spoon in a hot cup of coffee. The heat from the coffee goes straight into the spoon.
You can picture this using a simple idea: heat flows from hot to cold.
Convection is all about how heat moves in liquids and gases because they are in motion.
For example, when you boil water, the hot water rises to the top. Meanwhile, the cooler water sinks down to the bottom to take its place.
This creates a cycle. Stirring the water helps make this heat movement even better!
Radiation is different from the other two methods because it doesn’t need a medium like air or water to transfer heat.
Instead, heat moves through invisible waves.
For instance, when you feel warmth from the sun, that’s radiation at work!
In short, conduction happens through contact, convection involves fluid motion, and radiation uses waves to transfer heat. Each method helps us understand how heat works in our everyday lives!
