A portion of an electric circuit connected to a 60 ohm resistor is embedded in 0.50 kg of a solid substance in a calorimeter. The external portion of the circuit is connected to a 120 V DC power supply.
A) calculate the current in the resistor
B) calculate the rate at which heat is generated in the resistor.
C) assuming that all the heat generated by the resistor is absorbed by the solid substance, and that it takes 5 minutes to raise the temperature of the substance from 25 C to 85 C, calculate the specific heat for the substance.
