Thermodynamics – Solutions

1) Choose the correct answer. A thermodynamic state function is a quantity:

i) used to determine heat changes.

ii) whose value is independent of path

iii) used to determine pressure volume work.

iv) whose value depends on temperature only.

Solution

A thermodynamic state function is a quantity whose value is independent of path. It depends upon the initial and final states of the system. Hence, the correct option is (ii).

2) For a process to occur under adiabatic conditions, the correct condition is:

i) DT=0

ii) Dp= 0
