The Emperor penguin keeps its egg warm through the winter by holding it on top of its feet and under a brood pouch. The temperature inside the pouch is \(36 ^\circ \text{C}\). If this is \(78^\circ\) warmer than the outside temperature, what is the outside temperature?
After the baby penguin hatches, it needs to grow up for about 150 days before it can start swimming. The ice shelf melts away in the summer when the surrounding temperature reaches about \(\text-4^\circ \text{C}\). What is the difference between the summer and winter outside temperatures?
