4. A process in which no heat is exchanged between the system and surroundings is called an adiabatic process. In an adiabatic process, the system can still exchange energy with the surroundings, but only by means of work. Indicate whether each statement about an adiabatic process in a closed system is always true, always false, or true in certain conditions (specify the conditions): (a) AU = 0; (b) q = 0; (c) q is negative; (d) AU = q; (e) AU = w. = =
