Observe Energy Transfer Types Practice Test

Chen puts a metal spoon (destination) into a cup of hot soup (source). After a few minutes, the spoon handle feels warmer to his fingers. When he takes the spoon out, the handle is still warm for a short time. What evidence shows that energy is being transferred?

Maya claps her hands (source) near her friend Marcus (destination). Marcus hears a loud clap when he is close. When Marcus steps back several meters, the clap sounds quieter. In this observation, how is energy moving from one place to another?
