What is the main mechanism of heat transfer in liquids and gases?
Correct Answer: Convection
- Step 1: Understand that heat transfer is how heat moves from one place to another.
- Step 2: Know that there are three main ways heat can transfer: conduction, convection, and radiation.
- Step 3: Focus on liquids and gases, which are both fluids.
- Step 4: Learn that in fluids, heat transfer mainly happens through convection.
- Step 5: Understand that convection occurs when warmer parts of the fluid rise and cooler parts sink, creating a flow that transfers heat.
