SSC CPO 2023 PYQ — Question 83

The correct answer is option 1 i.e. 3600 KJ/h.

Actually, 1 kilowatt (kW) is equivalent to 3.6 megajoules per hour (MJ/h), not 3600 kilojoules per hour (kJ/h).

Here's the conversion:

1 kilowatt (kW) = 1000 watts (W)

1 kilojoule (kJ) = 1000 joules (J)

So, 1 kilowatt = 1000 joules per second (Watt definition)

= 1000 joules per second × 3600 seconds

= 3600 kilojoules per hour (kJ/h)

So, 1 kilowatt is equivalent to 3600 kilojoules per hour (kJ/h), not 3600 kJ/h.
