What energy is used with a 5000watt oven being used for 30 minutes?

Well, it's an easy enough math problem, so I'm just going to tell you *how* to do it.
1 Watt = 1 Joule/second
5 minutes = 5*60 seconds
Multiply so that the seconds cancel each other out. This is simpler to just do with dimensional analysis than to try to evaluate it in separate steps.

∙ 11y ago1 joule = 1 watt x 1 second. Therefore, you can convert the minutes to seconds, and multiply to get a result in joules.
Alternately, since electric companies charge by the kilowatt-hour, you can convert watts to kilowatts, minutes to hours, and then multiply to get kWh directly.

When a microwave oven timer beeps to what kind of energy has electricity been changed into?
The electromagnetic energy (electricity) the oven operates on is being converted into mechanical (sound) energy when the timer beeps.
Is food being heated in the oven a conversion from chemical energy to mechanical?
yes it is
What are energy conversions in a oven?
electrical energy of when you turn the oven on to thermal energy when it is heating up
Is an oven a example of chemical energy?
No. An oven is an example of thermal energy.
What is the most efficient type of oven?
Answer: There is no single best kind of oven. The best kind of oven depends on the product being baked, whether pizza, bread, pastries or cakes.Answer:For a home oven I would suggest a Viking.
How does energy efficiency of conventional oven compare to microwave oven?
compare microwave oven to conventional oven
What type of energy does a oven?
Thermal energy
What kind of energy transition is happening in an oven if the oven burns gas to cook food?
The burning of gas is chemical energy, and it creates thermal energy (heat, which is mechanical energy) to cook the food. Chemical energy is converted into thermal energy in the gas oven.
How is kinetic energy used in a microwave oven?
Kinetic energy is the mechanical energy (thermal energy) that does the heating/cooking in a microwave oven. The microwaves that the oven generates stimulate chemical bonds in food, and this is the conversion of electromagnetic energy into that heat we mentioned.
What energy changes occur in a microwave oven?
We find that in the microwave oven, electromagnetic energy (microwaves) are converted in thermal (heat) energy.
How is chemical energy transformed into thermal energy in a solar oven?
It isn't. A solar oven uses the rays from the Sun, not chemical energy.
Is thermal an energy?
yes because the oven heats the food inside the oven which makes is thermal energy
