What Happens When Dianne Holds Her Hand Near Dry Ice?

What is really happening when Dianne holds her hand near dry ice? The answer is A) Heat energy from Dianne's hand is being transferred to the dry ice even though she is not touching it.

Explanation:

In this example, we learn that Dianne feels cold when she holds her hand close to the dry ice. In fact, Dianne feels as if the cold is moving from the dry ice to her hand. However, this is not what is happening. Changes in temperature occur when heat is transferred from a warm body to a colder one. Therefore, what is actually occurring is that heat energy from Dianne's hand is being transferred to the dry ice even though she is not touching it, and this makes her feel cold.
