An electric immersion heater of 1.08 kW is immersed in water. After the water has reached a temperature of 100°C, how much time will be required to produce 100 g of steam ?

50 s 420 s 105 s 210 s

210 s

Power = 1.08 kW = 1080 W P × t = E            1080 × t = m × L 1080 × t = 100 × 540 × 42 t = 210 s
