3. The plates of a capacitor are charged to a potential difference of 5 V. If the capacitance is 2 mF, what is the charge on the positive plate?

4. A confined ideal gas undergoes a cyclical process in three steps—an isobaric step, followed by an isochoric step, followed by an isothermal step. Which of the following must be true?
