b) figure shows a thermodynamic process 10
which during the part ab, 600) of heat is
added to the system, and in the part bd, 2003
of heat is added. find :
80
i) the change in internal energy u in the part
ib.
it) the change in internal energy u in going 30
hrough abd, and
b) the total heat added in going through acd. [8]
