Question 73

A physicist suggests several ways to transfer energy to a small, stationary copper block resting on an insulating stand. They propose the following methods:

  1. Place the block in thermal contact with a hotter object.
  2. Direct a laser beam onto the surface of the block.
  3. Establish an electric current through the block.

Which of these methods successfully transfer energy to the block?

A

1 and 2 only

B

1 and 3 only

C

2 and 3 only

D

1, 2, and 3
