Bullfrogs are cold-blooded animals, which means that they release any excess heat generated through metabolism into their environment. A sedentary bullfrog being studied in a large laboratory aquarium kept at a constant temperature of 25°C transferred 100. J of energy reversibly to the water at 25 °C. What is the change in entropy of the water?

ANTICIPATE Because the water is absorbing energy as heat, you should expect its entropy to increase.

PLAN Use Eq. 1 to calculate the entropy change.

What should you assume? Assume that the aquarium is so large that its temperature remains virtually constant as the heat is transferred: Eq. 1 applies only at constant temperature.
