A small electric immersion heater is used to heat 62 g of water for a cup of instant coffee. The heater is labeled "110 watts" (it converts electrical energy to thermal energy at this rate). Calculate the time required to bring all this water from 25°C to 100°C, ignoring any heat losses. (The specific heat of water is 4186 J/kg-K.) Number i Units
