Radiation is a method of thermal energy transfer that moves -

• through empty space.
• when objects touch.
• only through solids.
• in the motion of fluids.

• both objects are in physical contact with each other.
• one of the objects is made of a metal.
• both objects are exactly the same temperature.

Which of the following is an example of conduction?
