1) THIS IS A THERMODYNAMICS QUESTIONS
1) A thermodynamic cycle is a set of steps that returns the system to the same state that it started from (see, for example, pages 118 and following in the text). For each of the following quantities, circle or highlight the correct phrase to indicate whether the quantity will always sum to zero when all steps of a thermodynamic cycle are included, or whether there may be situations where it doesn't sum to zero.
a) q, heat Always sums to zero Does not always sum to zero
b) dqrev/T Always sums to zero Does not always sum to zero
c) w, work Always sums to zero Does not always sum to zero
d) U Always sums to zero Does not always sum to zero
e) -pdV Always sums to zero Does not always sum to zero
f) H Always sums to zero Does not always sum to zero
g) G Always sums to zero Does not always sum to zero
Explanation / Answer
heat always sum to zero
dq rev /T always sums to zero
w work alway sum to zero
delta U alwaays sums to zero
Delta H aways to sum to zero
-Pdv always sum to zero
Deta G does not always sum to zero
