Question

Consider the following statements:

Assertion (A): If Ice collects on the freeze the cooling in the refrigerator is affected adversely.
Reason (R) : Ice is a poor conductor.

Select the correct answer using the codes given below:
Codes:

  1. Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
  3. (A) is true, but (R) is false.
  4. (A) is false, but (R) is true.

Answer:

Option A: Both (A) and (R) are true and (R) is the correct explanation of (A).

Detailed Solution:

The correct answer is “Both (A) and (R) are true and (R) is the correct explanation of (A).”.

Ice is a poor conductor of heat. So, when ice collects on the freezer, it acts as a barrier, preventing the heat from inside the refrigerator from being transferred to the cooling coils. This can cause the refrigerator to work harder and use more energy to maintain its desired temperature.

Therefore, ice on the freezer can adversely affect the cooling in a refrigerator.
