Consider the following statements and select the correct answer using ...
Assertion (A): If ice collects on the freezer, the cooling in the refrigerator is affected adversely.
Reason (R): Ice is a poor conductor.
The correct answer to this question is option 'A', which states that both the assertion (A) and the reason (R) are true, and the reason is the correct explanation of the assertion.
Explanation:
Assertion (A): If ice collects on the freezer, the cooling in the refrigerator is affected adversely.
When ice accumulates on the freezer, it acts as an insulator and reduces the efficiency of the cooling system in the refrigerator. Ice is a poor conductor of heat, and its presence on the freezer walls creates a layer of insulation. This insulation prevents the cold air inside the freezer from properly reaching the refrigerator compartment, leading to a decrease in cooling efficiency. As a result, the overall cooling in the refrigerator is adversely affected.
Reason (R): Ice is a poor conductor.
Ice is a solid form of water, and like other solids, it is a poor conductor of heat. Heat transfer occurs through three main mechanisms: conduction, convection, and radiation. In the case of ice, conduction is the primary mechanism by which heat is transferred. However, due to its molecular structure, ice has a low thermal conductivity. This means that it does not allow heat to pass through it easily.
When ice collects on the freezer walls, it acts as a thermal barrier, preventing the cold air from transferring heat effectively. As a result, the cooling in the refrigerator is affected negatively.
Conclusion:
In conclusion, the assertion (A) is true because ice accumulation on the freezer does adversely affect the cooling in the refrigerator. The reason (R) is also true because ice is indeed a poor conductor of heat. Furthermore, the reason provides the correct explanation for the assertion. Therefore, the correct answer is option 'A'.
Reason (R): Ice is a poor conductor.
The correct answer to this question is option 'A', which states that both the assertion (A) and the reason (R) are true, and the reason is the correct explanation of the assertion.
