Exploring Heat Transfer: Conduction, Convection, and Radiation

What is the first step to take before starting any experiment?

• Read the instructions

• Ensure lab safety

• Understand the theory

• Gather all materials

How does heat transfer occur in conduction?

• Through electromagnetic waves

• By direct contact of particles

• By the movement of fluids

• By radiation

In the example of cooking on a stove, how does the heat transfer to the food?

• By thermal expansion

• By convection

• By conduction

• Through radiation

What are fluids in the context of convection?

• Gases and solids

• Solids and plasmas

• Solids and liquids

• Liquids and gases

How does convection work in heating a pool?

• Hot water stays at the bottom

• Hot water rises and cools down, then moves back down

• Cold water rises and hot water sinks

• Water does not move
