At what rate per hour does a 1 kW heater convert electrical energy into heat?

At what rate per hour does a 1 kW heater convert electrical energy into heat? Correct Answer 3.6 MJ

Energy = power x time 1 kW is 1,000 watts Since 1 watt is 1 joule per sec 1,000 watts is 1,000 joules per sec In one hour there are 3,600 seconds Substituting in the equation energy = 1,000 x 3,600 joules = 3,600,000 joules = 3.6 MJ Therefore a 1 kW heater converts 3.6 MJ of electrical energy into heat per hour.

The following question consists of six sentences of a passage. The first and the sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly. S1: A single device can heat fluids without requiring an electrical element. S6: Because there is no electrical element, there is no risk of fire, so the system is suitable for dangerous environments. P: A heat exchanger transfers heat from the central cavity to an air heater, a water heater or an industrial processor. Q: It has a container like the crankcase of a car’s engine, which contains the fluid to be heated. R: Compression and friction at the nozzles heat the fluid so that the temperature in the central -cavity rises steadily. S: A motor and pulley inside the container turn a rotor wheel, which in turn forces the fluid again and again through narrow nozzles into a central cavity. The proper sequence should be
