A small electric immersion heater is used to boil 60.0 g of water for a cup of instant coffee. The heater is labeled 165.0 W, which means that it converts electrical energy to heat at this rate. Calculate the time required to bring this water from 13.5 °C to the boiling point ignoring any heat losses.
