The absolute zero pressure can be attained at a temperature of
A. 0°C
B. -273°C
C. 273 K
D. None of these
End states are determined by Internal Energy (U) levels at those states
i.e. dQ= dW + dU
For an adiabatic process dQ= zero.
Therfore |dW| = |dU|. In words, work done in an adiabatic process depends only on the end states (determined by U).
