Assertion: For cooking in a microwave oven, food is always kept in metal containers.
Reasion: The energy of microwave is easily transferred to the food in metal container.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reasion are true but reason is not the correct explanation of assertion.

C

If assertion is true but reasion is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
d
The atoms of the metallic container are set into forced vibrations by the microwaves. Hence, energy of the microwaves is not efficirently transferred to the metallic contain. Hence food in metallic containers cannot be cooked in microwave oven. Normally in microwave oven the energy of waves is transferred to the kinetic energy of the molecules. This raises the temperature of any food.

A : When cooking in microwave ovens, metal containers are used. R : Energy of the microwaves can be easily transferred to the food through metal.

Why a metal container should not be used in a microwave oven?

In a microwave oven, the food is kept in a plastic container and the microwave is directed towards the food. The food is cooked without melting or igniting the plastic container. Explain.

Assertion Microwaves are used in microwave oven for cooking purpose. Reason The frequency of microwaves is from 10^(14) to 10^(17) Hz .

Assertion : One should not use metal containers in a microwave oven Reason : Only because metal may melt form heating.

Assertion : Microwaves are heat waves which is used to heat up food in ovens. Reason : In ovens, microwaves heat up the vessel first and food inside gets heated up by the transfer of energy from the vessel.
