For all processes, both q and ΔE will have the same sign.

Question

Quizplus · Accepted Answer

This statement is false. q and ΔE can have opposite signs depending on the type of process. For example, in an endothermic process, q will be positive (heat is absorbed) while ΔE will be negative (internal energy of the system decreases). Conversely, in an exothermic process, q will be negative (heat is released) while ΔE will be positive (internal energy of the system increases).
