Question

Which material would result in the least amount of energy transfer?

A reflector that is bright in color and smooth.
A reflector that is dark in color and smooth.
An absorber that is bright in color and rough.
An absorber that is dark in color and rough.

Answer 1

The least amount of energy transfers by a reflector that is dark in color and rough is the correct option D.

A common example of energy transfer that we see in lifestyle is the transfer of kinetic energy—energy-related to motion—from one moving object to a stationary object via work.

Thermal energy transfers occur in three ways:

• Conduction
• Convection
• Radiation

Energy can't be created or destroyed, meaning that the entire amount of energy within the universe has always been and can always be constant.

Energy is transferred by one among the subsequent four sorts of energy pathways:

• Mechanical work – a force moving an object through a distance
  
• Electrical work – charges moving, to a possible difference
  
• Heating –temperature difference caused electrically or by reaction
  
• Radiation – energy transferred as a wave eg. light, infrared, sound - the Sun emits light radiation and infrared.

Therefore, the correct option is D means a reflector that is dark in color and rough results in the least amount of energy transfer.
