To compute the heat produced by a 2.5 kW (kilowatt) heating element, you can use the formula:
Heat (in kilojoules) = Power (in kilowatts) × Time (in hours) × Conversion Factor
In this case, the power is 2.5 kW. Let's assume we want to calculate the heat produced over a period of 1 hour. The conversion factor is used to convert kilowatts to kilojoules and is equal to 3,600 since there are 3,600 seconds in an hour.
Using the formula, we have:
Heat = 2.5 kW × 1 hour × 3,600
Heat = 2.5 × 3,600 kilojoules
Heat = 9,000 kilojoules
Therefore, a 2.5 kW heating element would produce 9,000 kilojoules of heat when operated for 1 hour.
