The freezing chest in refrigerator is kept near the top because
- Ait is convenient to use
- Bit reduces cost
- Cit cools the remaining space by the process of conduction.
- Dconvection currents are set up
Solution & Step-by-step Explanation
The freezing chest is placed near the top of a refrigerator to optimize heat transfer through convection currents. Air near the freezer becomes cold, contracts, and increases in density. This heavy, cold air naturally sinks toward the bottom of the refrigerator, displacing the warmer, less dense air below and forcing it to rise toward the top to be cooled. This continuous cyclical loop ensures uniform cooling throughout the entire compartment.
