Panremains in thermal equilibrium with the water

Reference no: EM13648020

An aluminum pan with 1.50 kg of water at an initial temperature of17 deg-C is placed on an electrical heater. Suppose it takes 4.50minutes to warm the water to boiling and convert 10% of the water to steam. The aluminum pan has a mass of 0.248 kg, and the panremains in thermal equilibrium with the water. The heater runs at avoltage of 115 V. What is the current required in the electricalheater to carry out this experiment in the time given? Assume thatonly 29% of the energy produced by the heater goes into warming thewater and the pan. The rest is lost to the surroundings.
