How long to boil water with an 1100W kettle when starting temperature is 15°C?
Suppose you wish to boil 1L of water to make tea. The water comes out of the tap at 15°C and you have an 1100W electric kettle.
a) How long will it take to boil the water?
b) Assume an electricity cost of 8.5 cents per kW-h, how much does it cost to boil the water?
Any help is greatly appreciated!
