Which of the following statements are true? If a statement is true only under special circumstances, label it as false. Select all that apply. ANSWER: If the temperature of the system increased, w>O If the temperature of the system increased, q>0 If work is done on a system the temperature always increases. Heat flow into a system always causes its temperature to increase. none
According to first law of thermodynamics
∆U = q + w
∆U = internal energy of system
q = heat released or absorbed by the system
w = work done by or done on system
From the first law of thermodynamics we know that ∆U is depends both on q and w but not resticted only to either q or w.
