How many watts per hour are in a kilowatt (K)?

  1. 100 watts per hour

  2. 1000 watts per hour

  3. 500 watts per hour

  4. 2000 watts per hour

The correct answer is: 100 watts per hour

A kilowatt (K) is a unit of power equivalent to 1000 watts. Therefore, the correct answer is A: 100 watts per hour. This is the conversion factor between kilowatts and watts, with one kilowatt being equal to 1000 watts. The other options provided do not accurately represent the conversion of kilowatts to watts and are therefore incorrect.
