1. A 500.0 g pot of water at room temperature (20.0C) is placed on a stove.
   1. How much heat (in cal) is required to change the temperature of liquid water from 20.0C to 100.0C?
   2. How much heat (in cal) is required to change this liquid water at 100.0C to steam at 100.0C?
2. A 0.25 kg length of aluminum wire is warmed 10.0C by an electric current. How much heat (in cal) was generated by the current? (C_aluminum = 0.022 cal/kg C) Final answer must be with 0 decimal places.
