Question

How do conduction and convection differ?

Group of answer choices

Conduction can move through empty space to transfer heat; convection cannot.

Conduction does not require objects to have direct physical contact; convection does.

Conduction requires objects to have direct physical contact; convection does not.

Conduction transmits heat through electromagnetic waves; convection does not.

Answer 1

Conduction requires objects to have direct physical contact; convection does not.

Step-by-step explanation:

Conduction, convection and radiation are modes and forms of heat transfer. These processes moves heat from one place to another.

• Conduction involves the movement of heat through bodies in contacts.
• As the molecules vibrates against one another, their thermal energy increases and heat is moved.
• Convection transfers heat in fluids i.e. liquids and gases. It utilizes temperature and density differences.
• Radiation does not involve the use of particles or a medium to propagate.
