1.5 kg of liquid water initially at 12∘C is to be heated to 95∘C in a teapot equipped with an 800-W electric heating element inside. The specific heat of water can be taken to be 4.18 kJ/kgK, 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) 5.9 min
(b) 7.3 min
(c) 10.8 min
(d) 14.0 min
(e) 17.0 min
