Question

In which of these systems is the entropy decreasing?liquid coolinair escaping from a tiresnow melting salt dissolving in water

Answer 1

liquid cooling.

Step-by-step explanation:

Remember that entropy can be interpreted as the degree of disorder or randomness in the system.

When we're releasing energy in form of heat in a spontaneous reaction (endothermic process), the entropy is increasing.

In a nonspontaneous reaction, we require energy from an external source (endothermic process), in this case, the entropy decreases.

Based on this logic, when we want to cool a liquid, we require energy to do it, so the entropy, in this case, decreases. The answer would be liquid cooling.
