Part A

Assume that the cell phone has a potential rating is about 3.8 V and a charge capacity is about 2600 mAh. What is the energy capacity for this cell phone?

Express your answer in watt-hours (Wh).

Part B

Convert the charge capacity Q into coulombs.

Express your answer in coulombs (C).

Part C

Convert the energy capacity U into kilojoules.

Express your answer in kilojoules (kJ).

Part D

If the charge Q were stored on a parallel-plate capacitor with air as the dielectric, at the potential V, what would be the corresponding capacitance?

Express your answer with the appropriate units.

Part E

If the energy in the battery were used to heat 1.0 L of water, estimate the corresponding change in the water temperature? The heat capacity of water is 4190 J/kg⋅K.

Express your answer in degrees Celsius.
