OneTenA, Inc. recently interviewed a candidate for an engineering position. He was asked to explain how the closed$-$system version of the first law of thermodynamics could be applied to the following scenario: a piston contains a gas that is very quickly expanded to three times its volume, after which its temperature is found to have decreased. He suggested that the work $$ associated with this process is large and positive as a result of the expansion, while the heat $$ is large and negative due to the temperature drop. The interviewing team was unhappy with his response to this and other questions, and needless to say, he was not hired. However, Management would like to document an appropriate answer for its records. Prepare a one$-$paragraph memo outlining the nature and sign of the terms $,,$ and $$ as applied to this scenario. Be sure to follow our corporate memo policy.
