Final answer:
The entropy change (δs) is positive when a piece of wax melts, as it involves a transition from a more ordered solid to a less ordered liquid state, thus increasing disorder.
Step-by-step explanation:
The question is regarding whether the entropy change (δs) is positive for the melting of a piece of wax. According to the principles of thermodynamics, when a solid melts into a liquid, its particles move from a more ordered state to a less ordered state, increasing the dispersal of energy and matter. Consequently, the entropy, which is a measure of disorder, increases during the melting process. Therefore, this process has a positive entropy change.
The change in entropy for the process of a piece of wax melting is positive. When a solid substance like wax melts, it undergoes a phase transition from a relatively ordered solid to a less ordered liquid. This change in state results in an increase in the randomness and disorder of the particles, leading to a positive change in entropy.
