QUESTION:

To heat 1 cup of water to make coffee,

ANSWER:

Solution 62P Step 1: This process involves the change in entropy. As we know that entropy is defined as the number of ways a system can be arranged. The higher the entropy more the system is disordered.If the process is reversible ,then the change in entropy is equal to the heat absorbed divided by the temperature of the reversible process. In the equation, Q is the heat absorbed, T is the temperature and S is the Entropy. This process involves irreversible heat flow because of the temperature heat flow.
