Q
Q: In which scenario does heat transfer occur through both conduction and convection?
Solution:
A hot cup of coffee cooling down involves conduction (heat transfer from coffee to cup) and convection (heat transfer from cup to air).
Steps: 5
Show Steps
Step 1: Imagine you have a hot cup of coffee.
Step 2: The coffee is hot, so it has a lot of heat energy.
Step 3: The coffee heats up the cup it is in. This is called conduction, where heat moves from the hot coffee to the cooler cup.
Step 4: The cup, now warm, heats the air around it. This is called convection, where warm air rises and cooler air moves in to take its place.
Step 5: As the coffee cools down, both conduction and convection are happening at the same time.
