°C to boiling point 100°C?
First, we need to calculate the amount of energy required to boil 1 kg of water:
Energy = mass x specific heat capacity x temperature change
Energy = 1 kg x 4.18 J/g°C x (100°C - 20°C)
Energy = 334.4 kJ
Next, we need to calculate the power of the electric kettle:
Power = current x voltage
Power = 4 A x 220 V
Power = 880 W
We can now use the formula:
Energy = power x time
Rearranging for time, we get:
Time = energy / power
Time = 334.4 kJ / 880 W
Time = 380 seconds or 6.33 minutes
Therefore, it will take approximately 6.33 minutes to boil 1 kg of water from room temperature 20°C to boiling point 100°C with an electric kettle that takes 4 A current at 220 V.
