Question

Assertion: One should not use metal containers in a microwave oven.
Reason: Only because metal may melt from heating.
a. Both assertion and reason are correct and the reason is the correct explanation for assertion.
b. Both assertion and Reason are correct but the reason is not the correct explanation for Assertion.
c. Assertion is correct but Reason is incorrect.
d. Both Assertion and Reason are incorrect.

Answer 1

Hint: Microwave heating is a multiphysics process involving electromagnetic waves and heat transfer in which any material subjected to electromagnetic radiation is heated.
In the microwave oven, every metal or conductive object will operate as an antenna to some extent, resulting in an electric current. As a result, the object becomes a heating element. This effect varies depending on the shape and composition of the object, and it is sometimes used in cooking.
Putting all metals in the microwave is not dangerous. Metals like forks, knives, and spoons are excellent conductors of electricity because they contain a large number of free-moving electrons. Microwaves are reflected when they touch metal things, which might pose complications.

Complete step-by-step solution:
The use of metal conductors in the microwave oven for heating is not recommended. It is possible to employ specifically made material for this purpose.
Metal containers should not be used in microwave ovens for a variety of reasons, including the risk of melting owing to extreme heat.
Another main reason is, Metals, on the other hand, are densely packed with electrons that may freely flow around, making them excellent electrical conductors. Due to the charge stored in the metallic container as a result of the electromagnetic waves, there is also a risk of electric shock.
As a result, while the Assertion is correct, the Reason is not.

Note:The metal of a microwave oven reflects the microwaves, concentrating them on the food to be cooked. Microwaves are absorbed by specific chemicals found in food.
Water, ceramics, and certain polymers are examples of materials that function well in this application, as they all successfully transform microwave energy into heat.
Furthermore, your microwave oven's interior walls are made of metal. This creates a Faraday Cage, which confines microwaves inside the box, allowing them to cook the food rather than the items around the microwave oven, such as you.
