3 kg of liquid water initially at 12°C is to be heated at 95°C in a teapot equipped with a 1200-W electric heating element inside. The specific heat of water can be taken to be 4.18 kJ/kg • °C and the heat loss from the water during heating can be neglected. The time it takes to heat water to the desired temperature is
(a) 4.8 min
(d) 9.0 min
(b) 14.5 min
(e) 18.6 min
(c) 6.7 min
