Conduction

The video explains that heat transfer occurs from hotter to cooler bodies. Conduction is a process where kinetic energy is transferred from particle to particle, requiring physical contact. It is one of the three methods of heat transfer, along with radiation and convection.

In which direction does heat naturally flow?

• It does not flow naturally

• From a hotter body to a cooler body

• From a cooler body to a hotter body

• In any random direction

What is the primary mechanism of energy transfer in conduction?

• Radiation

• Convection

• Chemical reaction

• Kinetic energy transfer between particles

Which of the following is necessary for conduction to occur?

• Magnetic field

• Presence of a vacuum

• Physical contact between bodies

• High humidity

How many methods of heat transfer are there?

• Two

• Four

• Three

• One

Which of the following is NOT a method of heat transfer?

• Evaporation

• Convection

• Conduction

• Radiation
