A dielectric material, such as Teflon , is placed between the plates of a parallel-plate capacitor without altering the structure of the capacitor. The charge on the capacitor is held fixed. How is the voltage across the plates of the capacitor affected? 1. The voltage decreases because of the insertion of the Teflon . 2. The voltage becomes infinite because of the insertion of the Teflon . 3. The voltage increases because of the insertion of the Teflon . 4. The voltage becomes zero after the insertion of the Teflon . 5. The voltage is not altered, because the structure remains unchanged.

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
