Using a 1-kw heater for one hour consumes more energy than using a 100-w bulb for twenty-four hours. select the best answer from the choices provided

Power is the amount of work done per unit of time. It will have units of Watts which is equal to Joules per second. We determine the energy of each system above by multiplying the power with time. We do as follows:

E(heater) =1000 W (1 hr) (3600s/hr) = 3,600,000 J
E(bulb) = 100 W (24 hr) (3600s/hr) =   8,640,000 J

Therefore, the answer would be false. It is the bulb that consumes more energy.

Gas is all around us which means that the atmosphere
