Please briefly explain why you feel this answer should be reported.

My oven is rated at 5000 W, or 5 kW. Two hours in my oven would correspond to

c. 10 kWh

More information is needed to answer this question:

kWh is a measure of energy and it derives itself from product of the power (in kW) and the time (hours). Where 1 kWh of energy is derived from a power of 1 kW over 1 hour.

Therefore, the answer to your question will be the power (rating) of the oven, in kW (!!!), multiplied by the 2 hours

There is not enough info given. I imagine that this is a follow on question about a previous question which had data about the oven.

zero if it's a solar oven

zero if it's a wood fired oven

zero if it's a gas fired oven

we need more information,

If it's an electric oven and we are given the input voltage (E) and the drawn current (I), or resistance (R) so we can calculate amperage via

E = IR

The wattage used is E•I or E²/R or I²•R (W)atts

The energy used is wattage times time or E•I•t or E²t/R or I²Rt W•hr

where t is in hours

to convert to kWh, just divide the energy by 1000

Any of the possible answers could be an oven energy usage, although the larger numbers represen

strial type ovens. A typical househol

t be in the 10 kWhr range for two hours of usage. (a 5000 Watt use rate)

10 kwh is the most reasonable answer

"the same oven" suggests there is a previous part of the question. You have decided to leave this out, making the question impossible to answer. Well done!

What same oven? You have to give us the info from the previous question !!!!!!! duh
