In
a non-flow process, work transfer from the system is 30 kJ and heat received by
the system is 90 kJ. Determine the change in the internal energy.
-80KJ
60KJ
80KJ
-60KJ
60KJ
Given:
Work transfer
from system, (W) = – 30 kJ
Heat received by the system, (Q) = + 90 kJ
Hence,
the correct option is (B).
