In process I, does the internal energy of the gas increase, decrease, or remain the same? In process I, is the heat transfer to the gas positive, negative, or zero? In process II, does the internal energy of the gas increase, decrease, or remain the same? In process II, is the heat transfer to the gas positive, negative, or zero? D. i. Is the change in internal energy in process I (ΔUI ) greater than, less than, or equal to the change in internal energy in process II (ΔUII)? (Hint: Is the absolute value of the temperature change in process I greater than, less than, or equal to that in process II?) Explain.
