Given:
Power, P = 0.5 kW = 500 W
Time, t = 20 minutes = 1200 seconds
To Find:
Heat generated by the heater.
Calculation:
- We know that heat is a form of energy, so we will calculate it by using the formula given below:
E = P × t
E= 500 x 1200
E = 600000 J
E = 600 kJ
- So the heat generated will be 600 kJ
