A 0.1-A current flows through of a copper wire of length 1.0 m for 20 minutes. The diameter of the wire is 1.0 mm. Assuming that all the heat dissipated in the wire during this time is transferred to 100 ml of water, calculate the change in the water temperature. The specific heat of water is 4186 J/(kg OC).
