A small electric immersion heater is used to boil 191.0 g of water for a cup of instant coffee. The heater is labeled 355.0 W, which means that it converts electrical energy to heat at this rate. Calculate the time required to bring this water from 12.0°C to the boiling point ignoring any heat losses.
