Problem 4PE
What is the change in internal energy of a system which does 4.50 × 105 J of work while 3.00 × 106 J of heat transfer occurs into the system, and 8.00 × 106 J of heat transfer occurs to the environment?
ANSWER:
Solution 4PE
Step 1 of 2
Net heat transfer,
Q = Qin - Qout
Here,Qin is heat transfer into the system and Qout is for heat transfer to the environment.
Substitute 3.0 x 106 J for Qin and 8.0 x 106 J for Qout solve for net heat transfer.
Q = 3.0 x 106 J - 8.0 x 106 J
= -5.0 x 106 J
