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?
Answer & explanation
Correct answer: option 4
Power = 1.08 kW = 1080 W
P × t = E 1080 × t = m × L
1080 × t = 100 × 540 × 42
t = 210 s
