### 4B 11

In an adiabatic process, no energy is transferred as heat. Indicate whether each of the following statements about an adiabatic process in a closed system is always true, always false, or true in certain conditions (specify the conditions): (a) delta U = 0; (b) q = 0; (c) q < 0; delta U = q; (e) delta U = w.

Is there a specific equation that you are supposed to use for this question? I'm confused on how to approach this question.

This is more of a conceptual question that is based on the equation for internal energy, delta U = q + w. Given that this is an adiabatic process, this would mean that q, energy transferred as heat, equals 0. Delta U would also equal 0, but only under the conditions that no work is done.

I would just go thru the conceptual things he covered in class relating those variables to each other like under what conditions each term is zero, therefore making
U equal to some other variable ....
